Proper nutrition is one of the factors which is limiting onion production. Onion yield and quality is affected by fertilization of macro and micro nutrients. Mineral nutrients, Nitrogen, phosphorous and Potassium are macronutrients which significantly affect onion production. Nitrogen and phosphorous fertilization significantly affect growth, yield and quality of onion. The requirement of mineral fertilizer varies from place to place, depending on different factors in the growing areas. Effective use of N, P and K fertilizer depends on soil condition, irrigation system, climatic factors and management factors. In all different research reports, it is described that onion is a heavy feeder for N, P, K and the application of these mineral elements enhance production significantly. The quality of onion, physiology and production is highly limited by fertilization of N, P and K fertilizers. Therefore, in this review the effect of mineral nutrition on growth, physiology and yield of onion are discussed and examined in detail.

Jatropha (Jatropha curcas L.) is an herbaceous plant, perennial, belonging to the family of Euphorbiaceaes. Jatropha’s extract is used for the harvest of fruits, high amount of nutrients and, if not properly fertilized, can lead to the impoverishment of the soil over the years of cultivation. Thus, in this present work, we have a concern with the importance of fertilization. The experiment was conducted under field conditions in the 2014/2015 agricultural year, in São Jorge do Patrocínio, State of Parana, Brazil. The experiment was conducted in a randomized block design with five replications and five treatments, totaling 25 installments. The treatments were as follows: organic fertilization (total rate: 2,800 g plant-1), mineral fertilizers with nitrogen, phosphorus and potassium (total rate: 174.4 g plant-1, and 13.2 g plant-1 of urea, 141.2 g plant-1 of superphosphate and 20 g plant-1 of potassium chloride), 75% organic fertilizer + 25% mineral, 50% organic fertilizer + 50% mineral, 25% organic + 75% mineral, applied at planting. Poultry litter was used as the organic fertilizer source, the nitrogen source was urea, the phosphorus source was superphosphate and, the potassium source was potassium chloride. Spacing of 2 × 2 m between plants and the pits with 30 × 30 × 30 cm. The evaluated variables were: plant height, stem diameter, contents macro and micronutrients in leaves. It can be concluded that there was no influence of mineral and organic fertilization on the initial growth of jatropha. As for the macronutrient levels, there were no significant differences for P and K. However, regarding the mineral fertilizer and the micronutrient content, there was a significant difference in Mn, in the treatment with total rate of mineral fertilizer and in the treatment with 25% organic fertilizer and 75% mineral fertilizer.

The present work evaluated the effect of soil (S) and foliage (F) applied potassium on the growth, yield, and quality of potato plants. Potassium was added in soil at the recommended rate for all the treatments combining mineral fertilizers with K-feldspar and biofertilizers, while foliar spraying included the application of potassium citrate (PC), potassium silicate (PS), and monopotassium phosphate (MP). The obtained results showed that plant height was highest following treatment with 100% mineral potassium fertilizer under the foliar application of MP, while the content of P, K, and total carbohydrates in leaves also increased with the same fertilization treatment. On the other hand, the highest values for number of stems and fresh and dry weight per plant, as well as the highest nitrogen content in leaves, were obtained after the addition of mineral potassium fertilizer and the foliar spraying of PC, regardless of the growing season. Yield parameters were positively affected by the combination of mineral potassium fertilizers (100% or 80% K2SO4 + 20% K-feldspar + biofertilizer) and the foliar spraying of MP, while the total nitrogen, protein, amino acids, potassium, phosphorus, and starch content of tubers were positively affected by the same mineral fertilizer treatments combined with foliar spraying of MP or CP. In conclusion, the application of mineral potassium fertilizer with foliar spraying of MP or CP increased most of the plant growth- and tuber chemical composition-related parameters. These results highlight the importance of potassium fertilizer regimes for achieving high tuber yields and improving the quality of tubers in a sustainable and cost-effective manner.

Full textAbstract:
Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

Studies to determine the effect of mineral, biomineral fertilizers and biological products on the content of nutrients (nitrogen, phosphorus and potassium) during the growing season in spring barley plants were carried out in 2015-2017 on leached heavy loam chernozem of Ulyanovsk region. The soil of the experimental site contained: humus 6.43...6.62 % (according to Tyurin), total nitrogen-0.26 % (according to Kjeldahl), mobile phosphorus and potassium-214 ... 228 and 101...117 mg/kg of soil, respectively (according to Chirikov), pHKCl – 6.3...6.8 (GOST 26483-85), hydrolytic acidity – 1.20...1.29 mmol/100 g of soil (according to Kappen).
The scheme of the experiment included the following options: without fertilizers (control); Bisolbiphite (seed inoculation); N15P15K15 (regular azofoska); N15P15K15m (azofoska modified with BisolbiPhite); N7,5P7,5K7,5m (azofoska modified with BisolbiPhite in a half dose). We used a complex mineral fertilizer-azofoska in a dose of 15 kg d. v. per 1 ha of nitrogen, phosphorus and potassium and a microbiological preparation BisolbiFit, which serves as a modifier of seeds and mineral fertilizers. The drug is based on a strain of bacteria of the rhizosphere Bacillus subtilis H-13, isolated from chernozem soil. Inoculation of spring barley seeds with a biological preparation was carried out 1...2 days before sowing (400...600 g/t of seeds), mineral fertilizer was treated on the day of its application to the soil (4 kg/t of fertilizers). As the studied crop, the variety of spring barley Nutans 553, zoned in Ulyanovsk region, was sown on experimental plots. Mineral fertilizers and biological preparation had a positive effect on the nutrient content of spring barley plants. Under the influence of the studied fertilizer, the nitrogen content in the green mass of barley increased by 0.09...0.30%, phosphorus − by 0.09...0.18%, potassium-by 0.25...1.10 %, in relation to the variant where mineral fertilizer and microbiological preparation were not used. As a result of the correlation analysis, a positive relationship was established between the yield of barley and the content of nutrients in plants during the tillering, tubing and flowering phases: with nitrogen (r = 0.78; 0.83; 0.75), phosphorus (r = 0.80; 0.42; 0.71) and potassium (r = 0.66; 0.59; 0.91). As a result of this research work, it was found that the use of the studied fertilizers and the biological product BisolbiFit positively affected the content of the main nutrients (nitrogen, phosphorus and potassium) in spring barley plants in all phases of its development.

Full textAbstract:
The efficiency of mineral fertilizers depends upon various factors, one of which is fertilization method. In heterogeneous condition of fields of nutrient content, the benefits of variable rate fertilization will increase, cause as much fertilizer will be applied to each section of the field as is necessary specifically on this section to obtain the planned yield. Experimental results have revealed the following features: variable rate fertilizer of nitrogen to reduce the variability of the nitrate nitrogen content in the tillering phase of spring wheat to 36% relative to the content before sowing, variable rate fertilizer of phosphorus and potassium to reduce variability of labile phosphorus and potassium in soil to the phase of wheat harvesting by 11 and 21%. The fertilization of one rate is less effective. This method leads to a decrease in the variability of nitrate nitrogen to 48%, labile phosphorus by 10%, by variability of labile potassium increases by 17% in the same time. Yield of spring wheat was 4.36-4.46 t / ha with a protein content of 14.03-14.57%, wet gluten 33.0-35.0%, glassiness 87-88%, weight of 1000 grain 36.1-36.3 g were applied with variable rate fertilizers in off-line mode.

This study determined the changes in soil nutrients, organic carbon, organic matter and heavy metals during the early development stages of maize fertilized with different sources and doses. Also, this study confirmed that the used biosolid in the formulation of organomineral fertilizer makes greater efficacy than the effects promoted by mineral or filter cake organomineral fertilizers already used in agricultural. The experiment was done in a greenhouse at the Federal University of de Uberlândia - Campus Umuarama. The experimental design was randomized block design, as a 2 x 5 + 2 factorial, containing two sources of organomineral fertilizer consisting of organic residues (biosolid and filter cake), five doses of organomineral fertilizer (60, 80, 100, 120 and 140% of P2O5 recommendation for maize crop), a positive control with mineral fertilization (100%) and a negative one with no fertilization with four replications. The soil pH and contents of phosphorus, potassium, calcium, magnesium base saturation, base sum, micronutrients, organic carbon, organic matter and heavy metals were determined subsequently after plant removal, 65 days after sowing. The organomineral fertilizers based on biosolid and filter cake yielded increases in phosphorus, boron and manganese in the soil, especially the biosolid source. Regardless of the fertilizer organic matter source, soil phosphorus increased linearly with increasing doses of the sources. Doses equal or below the recommendation for maize (100% P2O5) were less effective in supplying potassium. The organomineral sources did not add heavy metals to the soil. Fertilizers based on biosolid can supply nutrients, such as phosphorus, boron and manganese at high doses, replacing mineral fertilization, while maintaining and improving soil fertility with no contamination by heavy metals.

Controlling the release rate of the nitrogen-phosphorus-potassium (NPK) for the soil fertilized can enhance the fertilizer efficiency and reduce the drawback for the environmental. In this work, a novel slow-release organo-mineral fertilizer was produced from the vinasse, which was blended with the NPK and the chitosan-bentonite matrix. The NPK used as additional nutrients source and the chitosan-bentonite matrix was performed as a barrier to prevent the nitrogen, phosphorus, and potassium from a rapid dissolving. The NPK release rate was measured and analyzed after 3, 6, 9, and 12 days using the incubation method and leaching test. The most efficient release rate was obtained when a dry vinasse mixed with 9% NPK and 5% chitosan-bentonite matrix with the ratio of 8:2. The vinasse-based slow-release of organo-mineral fertilizer (SR-OMF) was compared to the vinasse organo-mineral fertilizer (OMF). The result indicated that the NPK release rate in the vinasse-based SR-OMF was lower compared to that in the vinasse OMF.

Full textAbstract:
The aim of the research is to study the intensity of heavy metals accumulation in milk thistle leaf mass under fertilization with the latest types of fertilizers and to assess the environmental safety of such raw materials. Two experiments were laid in the research: the effect of fertilizing milk thistle with organo-mineral fertilizer Growth-concentrate on the intensity heavy metals accumulation by its leaf mass; the effect of fertilizing milk thistle with chelated fertilizers Phosphorus-chelate and Potassium-chelate on the intensity on heavy metals accumulation by the leaf mass. The use of a chelated Phosphorus chelate fertilizer for the fertilization of milk thistle crops leads to a 1.1 times decrease in the contamination of its leaf mass with cadmium and copper in comparison with the option without fertilizing its crops, and the increase in the concentration of lead and zinc compared to the control is insignificant and is within the range errors of experience. The use of fertilization of crops of milk thistle chelated fertilizer Potassium-chelate helps to reduce the contamination of its leaf mass with cadmium compared to the control, and the change in its contamination with copper is within the margin of error. At the same time, replacing the Growth-concentrate fertilizer with Phosphorus-chelate or Potassium-chelate when fertilizing milk thistle crops will lead to a decrease in the contamination of its leaf mass with lead, cadmium and copper, but will increase the contamination with zinc, compared to the control. The most environmentally safe leaf raw material of milk thistle in terms of lead, cadmium and copper content will be observed when fertilizing its crops with chelated fertilizers Phosphorus-chelate, and in terms of zinc content – when fertilizing with organo-mineral fertilizer Growth-concentrate. It is advisable to use Phosphorus-chelate fertilizer for the plant fertilization to reduce the contamination of the leaf mass of the medicinal raw material of milk thistle with heavy metals, in particular cadmium – by 9 % and copper – by 11 %,. To reduce contamination of the leaf mass with zinc by 81 %, it is recommended to use the organic-mineral fertilizer Growth-concentrate. Key words: milk thistle, medicinal raw materials, environmental safety, heavy metals, pollution, fertilizers.

Abstract The article presents the results of investigations carried out in a field experiment on sod-podzolic sandy soil contaminated with radionuclides, the efficiency of influence of doses and kinds of potassium fertilizers on the yield, 137Cs accumulation and fodder value of yellow lupine was studied. The carried out researches showed that the optimum doses of phosphorus-potassium fertilizers for getting an increased yield of green mass is P45K150, in both studied types of potassium fertilizers. To get the maximum grain yield of lupine, the optimal doses of mineral fertilizers are P45K150 and P45K210. Analyzing the effect of different types of potassium fertilizers on the formation of yellow lupine grain yield, it can be noted that the use of potassium fertilizer - Kalimag, the yield was higher than that of potassium chloride. To decrease accumulation of 137Cs in lupine green mass below permissible level, the doses of mineral fertilizers shouldn’t be less than P45K150. Maximum decrease of radionuclides in the grain was noted in the variant P45K210 (Kmg).

Revegetating abandoned peatlands plays an important role in reducing the CO2 footprint. One possibility for carbon reduction is cultivating blueberries as calcifuge plants in acidic peat soil. The aim of the experiment was to find out the effect of different fertilizers on half-highbush blueberry cultivar ‘Northblue’ growth and biochemical parameters in peatland conditions. The experiment was carried out in 2011–2015 with four organic and one mineral fertilizer, where three were composted chicken manure- and one maltose-based organic fertilizer. The soil of the experimental area belongs to the soil subgroup Fibri–Dystric Histosol with the peat layer 1.0–1.5 m deep. Organic fertilizer 4–1–2, which contained seaweed but had low phosphorus and potassium content, resulted in high yields in 2011 and 2013, with similar vegetative growth and comparable biochemical parameters as mineral fertilizer 6–14–23. The principal component analysis showed that the experimental year was more important in determining fruit parameters than the fertilizer type. However, our results indicated that the organic fertilizers are alternatives to mineral fertilizer for organic production.

The results of a field experiment held on podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine, studying the effect of various fertilization systems on the water-holding capacity of sugar beet, are presented. It was found that the change in nitrogen, phosphorus and potassium nutrition has a different effect on this indicator when closing the leaves of sugar beet plants between rows and during the harvest time. Half-dead cattle manure KRS on straw bedding aw well as mineral fertilizers, namely aqueous ammonia, ammonium nitrate, granular superphosphate, mixed potassium salt, potassium chloride, ANP fertilizer grade A and liquid complex fertilizer grade 10–34–0 were used during the experiment. Manure was applied at a dose of 40 t / ha and mineral fertilizers – N120Р120К120. Fertilizers were applied in August during fall plowing, as well as in late autumn (at the end of October) together with moldboard-free loosening of the soil to a depth of 14–16 cm and in spring –under pre-sowing cultivation. The dynamics of the intensity of water return was monitored by cut sugar beet leaves under conditions of rapid natural evaporation by weighing them every 0.5, 1 and 2 hours (according to Arland's method). It was found that the leaves of sugar beet, both with insufficient and unbalanced nitrogen nutrition, have a weak water-holding capacity during the growing season. Improving phosphorus nutrition, especially when applying liquid complex fertilizer grade 10–34–0, helps increase the water-holding capacity of sugar beet plants throughout the growing season. Replacing potassium chloride with potassium salt mixed as part of a complete mineral fertilizer significantly increases the water-holding capacity of sugar beets due to the better provision with sodium. This is particularly evident in the second half of the growing season. With the age of sugar beet plants, a distinct decrease in the intensity of water loss is observed regardless of fertilization, which can be explained by an increase in the content of bound water due to a rise of the amount of dry matter.

Experimental studies on the decontamination and stabilization of sludge sites sediment with calcium oxide treated with disinfectant. The results of the research discovered that the sewage sludge of Voronezh City is safe and can be used as organic fertilizer for growing agricultural plants. Determination of the content of macro-elements of mineral nutrition in the soil and the reaction of its environment showed that the application of organic fertilizers in the form of sludge increases the amount of nitrate nitrogen, exchangeable potassium, mobile phosphorus in the soil compared to the non-fertilized sample. Contemporaneously, the mass fraction of impurities of toxic elements in the soil decreases when the sewage sludge is used as an organic-lime fertilizer.

Aims - The farming intensification in Sub-Saharan Africa induced soil fertility and crop yields depletion such as cassava, a main food and an important source of income of farmers in Central Africa Republic. To transcend the soil fertility depletion and improve cassava yield, LaSBAD has initiate a study focused on the mineral fertilizers of cassava crops. Methods - Four types of fertilizer were tested: the urea (Co(NH2)2), the potassium sulfate (K2SO4), the potassium chloride (KCl) and the triple superphosphate (TSP). The methodology consisted in the physical and chemical analysis of soil, the cultivation, the application of mineral fertilizers and the harvest of cassava after 12 months. Additionally, the evaluation of the organoleptic propriety of raw tubers and cassava balls after the use of fertlizers were achieved throughout semi-strucrured interviews. Results - The contribution of nitrogen and phosphorus has increased very significantly cassava yield from 18.70 to 40.20 t/ha respectively for the control treatment (T0) and the best treatment obtained (T10). A significant interaction was observed between nitrogen (N) and potassium (K) inputs on yields. The increasing doses of potassium as potassium chloride (KCl) had reduced cassava plant growth and yield. According to respondents, the organoleptic proprieties of cassava were remain quite unchangeable by mineral fertilizers. Conclusion - The application of mineral fertilizer improved cassava yield and did not affected the organoleptic quality of the raw tubers and cassava ball. Nevertheless, further studies are needed to prevent soil degradation, namely the potential use of termite nest as natural fertilizers and legumes in association or rotation with other crops.

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment

The article presents the results of studying the effect of applying organic and mineral fertilizers on irrigated chestnut soils of the Ganja-Gazakh region to remove nutrients from the soil by grape harvest and dry pruning material. It was found that, along with an increase in yield, organic and mineral fertilizers also influenced an increase in the amount of nutrients removed from the soil. In comparison with the control variant without fertilizing, the amount of grape nitrogen removed by the crop in the experimental variants with fertilizer ranged from 7.7–24.0, phosphorus 1.5–6.3 and potassium 8.0–25.1 kg/ha, and the material of dry pruning is the amount of removed nitrogen is 18.6–46.5, phosphorus is 12.8–31.9, and potassium is 33.8–78.3 kg/ha.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The problem to provide the livestock industry of the North-West of Russia with forage grain has sharply escalated since 2010. Its successful solution is connected with the level and validity of the use of mineral and organic fertilizers. The purpose of the study, started by the Menkovsky Branch of the AFI in 2012, was to find effective options for the use of new organic-mineral fertilizer (OMF) which provides maximum agronomic effect and can produce grain of high quality. The methodological basis was the micro trials in polyethylene vessels without bottoms of 1 × 1 × 0.4 m in size with an artificially formed upper part of the profile of degraded sandy sod-podzolic soil. The soil was of 4.75 рНKCl, 3.46 mmol (eq) of Ng per100g, 3.20 mmol (eq) of Sch per100g, 1.83% of humus, 217 mg / kg of mobile compounds of phosphorus and 92 mg / kg of potassium. In the course of research, there was high agronomic efficiency of its use for winter wheat and satisfactory agronomic efficiency of its use for barley. When the winter wheat variety ‘Moskovskaya 56’ was fertilized with 5 t/ha of organic-mineral fertilizer containing 2.46% of Ng, 4.51% of P₂O₅ and 3.36% of K₂O, grain yield increased in 2.6 times. Fertilized with N75P50K50 the productivity improved in 3.8 times with a payback of 1 kg of NPK 7.4 and 5.6 grain units, respectively. It has been established that the combination of OMF with mineral fertilizers is accompanied by a significant yield increase with a decrease in its relative contribution from 153% to 59% and from 143% to 105% and a payback of 1 kg of NPK from 3.8 to 2.6 and from 6.9 to 4.7 of barley grain units and winter wheat grain units, respectively. The best indicators of the agronomic efficiency of OMF, both when applied in pure form and when fertilized with N75P50K50, corresponded to a dose of 4 t / ha. It has been found that the addition of 10 kg of potassium (К₂О) per 1 ton to OMF provided yield increase on 15% and the payback period of 1 kg NPK increased from 6.4 to 8.4 grain units. Qualitative indicators of wheat and barley grain fertilized with OMF improved due to the rise of raw protein percentage on 8–27% and a number of ash elements, such as CaO (from 0.07 to 0.11 mg/kg), MgO (from 0.16 to 0.21 mg/kg), Zn (from 21.5 to 23.6 mg/kg).

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions of the Volga forest-steppe. According to the organic fertilization system, straw of the predecessor, green manure and Biocomposite-correct were introduced into the soil (typical medium-thick medium loamy chernozem) for green manure mass (vetch-oat mixture). The organo-mineral system included two options: straw applied together with nitrogen in a dose of 10 kg per 1 ton of straw and zeolite enriched with amino acids. The mineral fertilizers were nitrogene phosphorus with the NPK content of 16 kg ai/ha, carbamide and potassium chloride. In addition, highly siliceous rock zeolite was applied as a fertilizer. It was found that the use of organic and organomineral fertilizers improves the nutrient regime of the soil; in terms of the content of nitrogen, phosphorus and potassium in the arable layer, these options were not inferior to the option with the use of mineral fertilizers. When introducing zeolite enriched with amino acids, the yield of winter wheat exceeded the option with the use of mineral fertilizers by 0.59 t/ha. The use of organic and organo-mineral fertilizers contributes to the production of environmentally friendly products

The use of mineral fertilizer in horticultural crops is a very important issue due to its effects on crop yield and its environmental impact. For the period 2011-2012, the total mineral fertilizer consumption in EU-27 reached 10.4 million tons of nitrogen (N), 1.0 million tons of phosphorus (K) and 2.2 million tons of potassium (K). Though many recent studies have examined horticultural crops, few have focused on mineral fertilizers in order to make an environmental assessment of a tomato crop. Therefore, the aim of this research was to study the agronomical (i.e. yield) and the environmental performance of a horticultural tomato crop fertilized with four different doses of mineral fertilizer (N0, N1, N2 and N3), using Life Cycle Assessment methodology. Data and conditions for the crop were taken from a real field trial with an experimental design carried out in North-east Catalonia, Spain. Following the guidelines of the ISO 14044, the study considered all stages of the life cycle of a horticultural tomato crop (i.e. mineral fertilizer production, transport and cultivation phase). Six impact categories were included in the study: climate change, photochemical oxidation formation, land acidification, freshwater and marine eutrophication and fossil depletion. Overall, the results showed that the best result was for the N1 treatment, with a yield of 61 ton ha-1 and 55 ton ha-1 for total and commercial yield, respectively. N1 showed the best environmental performance in all categories assessed.

This paper discusses the effect of a multiple-nutrient fertilizer and a mixture of simple mineral fertilizers on yield increase and forage quality improvement of hayfields under the conditions of the mid-mountain zone of the Republic of Altai. The natural forage lands of the mid-mountain zone of the Republic of Altai are characterized by the predomi-nance of the motley grass-grasses type of vegetation. The soils are deficient in available phosphorus and have in-creased exchangeable potassium content, so it is advisa-ble to apply mineral fertilizers containing nitrogen and phosphorus. The research was conducted from 2018 through 2020 on the farm of the KFK “Yegarmina M.M.” in the Shebalinskiy District of the Republic of Altai. In the var-iants of ammonium phosphate fertilizer application and its combination with ammonium nitrate in the rates of 20 and 40 kg ha (primary nutrient basis), yield increase of 24.1-85.9% (0.72-2.56 t ha) was obtained. The mineral fertilizers not only increase the yields, but also improve the nutritional value and forage quality. Digestible protein content in one fodder unit increased by 15-35 g as compared to that of the control. The maximum value of this indicator (116 g) was recorded in the variant with N12P52. Thus, the application of mineral fertilizers made it possible to obtain forages that met animal nutrition requirements.

A research study was established at the research farm of the University of Agriculture, Peshawar during winter 2018–2019. Commercial biochars were given to the experimental site from 2014 to summer 2018 and received 0.95, 130 and 60 tons ha−1 of biochar by various treatments viz., (Biochar1) BC1, (Biochar2) BC2, (Biochar3) BC3 and (Biochar4) BC4, respectively. This piece of work was conducted within the same study to find the long-term influence of biochar on the fertility of the soil, fixation of N2, as well as the yie1d of chickpea under a mung–chickpea cropping system. A split plot arrangement was carried out by RCBD (Randomized Complete Block Design) to evaluate the study. Twenty-five kilograms of N ha−1 were given as a starter dosage to every plot. Phosphorous and potassium were applied at two levels (half (45:30 kg ha−1) and full (90:60 kg ha−1) recommended doses) to each of the four biochar treatments. The chickpea crop parameters measured were the numbers and masses of the nodules, N2 fixation and grain yield. Soil parameters recorded were Soil Organic Matter (SOM), total N and mineral N. The aforementioned soil parameters were recorded after harvesting. The results showed that nodulation in chickpea, grain yield and nutrient uptake were significantly enhanced by phosphorous and potassium mineral fertilizers. The application of biochar 95 tons ha−1 significantly enhanced number of nodules i-e (122), however statistically similar response in terms of nodules number was also noted with treatment of 130 tons ha−1. The results further revealed a significant difference in terms of organic matter (OM) (%) between the half and full mineral fertilizer treatments. With the application of 130 tons ha−1 of biochar, the OM enhanced from 1.67% in the control treatment, to 2.59%. However, total and mineral nitrogen were not statistically enhanced by the mineral fertilizer treatment. With regard to biochar treatments, total and mineral N enhanced when compared with the control treatment. The highest total N of 0.082% and mineral nitrogen of 73 mg kg−1 in the soil were recorded at 130 tons ha−1 of biochar, while the lowest total N (0.049%) and mineral nitrogen (54 mg kg−1) in the soil were recorded in the control treatment. The collaborative influence of mineral fertilizers and biochars was found to be generally non-significant for most of the soil and plant parameters. It could be concluded that the aforementioned parameters were greater for treatments receiving biochar at 95 tons or more per hectare over the last several years, and that the combination of lower doses of mineral fertilizers further improved the performance of biochar.

The influence of different fertilizer forms and rates on nitrogen, phosphorus and potassium contents, nitrate accumulation and yield in red head chicory (Cichorium intybus var. foliosum L.) was investigated. Field fertilization trials were set up at two localities inNorthwest Croatia in 1999 and 2000. Trials were laid out according to the Latin square scheme in five fertilization treatments: manure 5 kg/m2, three rates of complex mineral fertilizer NPK (5:20:30) – 50, 100 and 150 g/m2, and an unfertilized control variant. The results of investigations indicate that there were no significant differences between treatments in the plant nitrogen and phosphorus contents. Significant fluctuations of the chicory potassium content (3.27–4.75% K) depending on the fertilization variant were recorded only in 1999 while in 2000 all values (4.13–5.12% K) were uniform. Plant nitrate levels were influenced by weather conditions more significantly than by the form and rates of fertilizers. All the recorded values are within the limits tolerated for leafy vegetables. Comparing the trial years, yields were generally higher in 1999 (1.58–4.95 kg/m2) than in 2000 (0.40–2.70 kg/m2). No significant differences in yield were recorded between the application of stable manure and the lowest mineral fertilizer rate.

Abstract: The objective of this work was to evaluate the effects of organomineral and mineral fertilizers, in their solid and fluid forms, on soils with variable charges with high fertility built up from nitrogen, phosphorus, and potassium contents in the soil and plant, as well as on corn (Zea mays) and black oat (Avena strigosa) yield. The treatments consisted of one control and four fertilizers - two organomineral and two mineral - in solid (SO, solid organomineral; and SM, solid mineral) and fluid (FO, fluid organomineral; and FM, fluid mineral) forms applied in Rhodic Kandiudox and Distrochrept soils with no-tillage. The use of organomineral or mineral fertilizers in fluid and solid forms increases total N content in the soil, maintains exchangeable K content in both soils, and may enhance available P content to the depth of 0.6 m in Distrochrept. These factors allowed significantly increasing corn yield, regardless of the fertilizer, and establishing greater residual effect for fluid organomineral fertilizer in the winter black oat yield, even in soils with high fertility.

AbstractThe experimental plots used in the study were located in the middle forest zone (elevation: 900-950 m a.s.l.) on two nappes of the flysch Carpathians in southern Poland. The aim of this study was to assess the effects of serpentinite in combination with nitrogen, phosphorus, and potassium fertilizers on selected chemical properties of the soil and activity of dehydrogenase and urease in the studied soils. All fertilizer treatments significantly enriched the tested soils in magnesium. The use of serpentinite as a fertilizer reduced the molar ratio of exchangeable calcium to magnesium, which facilitated the uptake of magnesium by tree roots due to competition between calcium and magnesium. After one year of fertilization on the Wisła experimental plot, the pH of the Ofh horizon increased, while the pH of the mineral horizons significantly decreased. Enrichment of serpentinite with nitrogen, phosphorus, and potassium fertilizers stimulated the dehydrogenase activity in the studied organic horizon. The lack of a negative effect of the serpentinite fertilizer on enzyme activity in the spruce stand soil showed that the concentrations of the heavy metals added to the soil were not high enough to be toxic and indicated the feasibility of using this fertilizer in forestry.

Sugar beet cultivars have different responses in various environments, such as different locations, years, mineral nutrition treatments or the combination of these factors, due to genotype ? environment interaction. Additive main effect and multiplicative interaction (AMMI) is one of the most commonly used multivariate methods for analysis and visualization of genotype ? environment interaction data. The main goals of the present study were to (i) investigate the application of AMMI method in the analysis of genotype ? fertilizer interaction in sugar beet, (ii) to assess genotype ? fertilizer interaction, and (iii) to identify sugar beet cultivars with the most stable response and high yield performance across different mineral nutrition treatments. The trial with eight sugar beet cultivars was conducted in two successive growing seasons at Rimski sancevi, Serbia. The different levels of nitrogen, phosphorous and potassium fertilizers (0, 50, 100 and 150 kg ha-1) and their combinations represented specific environments for testing genotype ? fertilizer interaction. Results from the analysis of variance indicated that the fertilizer treatment, cultivars, and their interaction significantly affected root yield variation in both seasons. Results from our study suggest that AMMI model with two and three first IPCA axes were recommended in 2014 and 2015, respectively. According to AMMI 1 and AMMI 2 biplot, E14 and E15 were high yielding and among the most stable treatments in both years. Among high yielding genotypes in 2014, G4 and G8 stand out as the most stable, while in the following year G3 had the lowest interaction score. AMMI analysis enabled identification of specific associations between cultivars and different mineral nutrition treatments, which was important for adjustment of fertilizer management for each cultivar in order to achieve high root yield with decreased and more rational fertilizer doses.

The article shows the influence of mineral and organic fertilizer norms on gray–brown soils and changes in the nutritional regime in winter wheat soils under irrigation in the Ganja–Gazakh region. It was found that the application of mineral and organic fertilizers for winter wheat in gray–brown soils significantly affected the change in the nutrient regime of the soil, significantly increasing the amount of nutrients easily absorbed by plants in the plowed and subsoil layers of the soil, as compared to the control (unfertilized) option, effective fertility increased, which in turn had a significant impact on productivity. At the end of the growing season, depending on the norm of mineral fertilizers in the soil layer 0–60 cm, ammonia nitrogen is 13.1–14.1, nitrate nitrogen is 7.2–7.4, mobile phosphorus is 7.0–8.0 and exchangeable potassium — 15.6–19.2 mg/kg, depending on the rate of organic fertilizers at the end of the growing season, ammonia nitrogen 12.6-–13.7, nitrate nitrogen 5.3–5.7, mobile phosphorus 6.2–6.6 and metabolic potassium while it increased by 20.4–21.2 mg/kg.

Reinforcing and optimizing sustainable food production is an urgent contemporary issue. The depletion of natural mineral resources is a key problem that is addressed by recycling mined potassium and phosphorus, and nitrogen, whose production depends on very high energy input. A closed-loop approach of fertilizer use asserts the necessity for efficient management and practices of organic waste rich in minerals. Human-derived urine is an underutilized yet excellent source for nitrogen fertilizer, and, in this study, processed urine fertilizer was applied to greenhouse soilless cultivation of lettuce (Lactuca sativa L.) cv. Grand Rapids. Biomass increase, biometric parameters, soil plant analysis development (SPAD) index, minerals, and organic acids content of lettuce were analyzed. From eight different urine fertilizer products generated, K-struvite, urine precipitate-CaO, and the liquid electrodialysis (ED) concentrate supported the growth of lettuce similar to that of commercial mineral fertilizer. ED concentrate application led to the accumulation of potassium (+17.2%), calcium (+82.9%), malate (+185.3%), citrate (+114.4%), and isocitrate (+185.7%); K-struvite augmented the accumulation of magnesium (+44.9%); and urine precipitate-CaO induced the highest accumulation of calcium (+100.5%) when compared to the control, which is an added value when supplemented in daily diet. The results underlined the potential of nitrogen- and phosphate-rich human urine as a sustainable source for the fertilization of lettuce in soilless systems.

Soil acidification in agroecosystems is a natural process that could be accelerated, mainly by the inappropriate application of mineral fertilizers, or prevented, by sustainable management practices. On the basis of a three-year field study in a grassland agroecosystem, the impact of different rates of fertilization with nitrogen (N), phosphorus (P), and potassium (K) on soil chemical parameters related to soil acidity was evaluated. It was found that high-rate fertilization with ammonium nitrate accelerated the soil acidification process, which was additionally intensified by the application of superphosphate and potassium salt. The sum of exchangeable base cations, the values of base saturation and hydrolytic acidity in the soil reflected the interactions between the applied NPK-fertilizer levels. Considering chemical parameters related to soil acidity studied in this experiment, it seems that the best strategies for mitigating soil acidification in grasslands are reducing nitrate leaching, changing fertilizer types and increasing the input of base cations.

The field experiment was conducted in central-eastern Poland. The aim of the research was to determine the effect of low-energy lignite organic matter applied to the preceding crop in the form of an organomineral fertilizer on the treatment optimization of Zea mays L. maize grown for silage. Two factors were taken into account in the research: factor I—five fertilization plots control plot—without fertilization (1), NPKMgS (2), NPKMgS + N1(3), NPKMgS + N2 (4), NPKMgS + N3 (5); factor II—three varieties of Zea mays L. Nitrogen was applied as fertilizers 3, 4 and 5 at doses of N1-20, N2-40 and N3-60 kg per hectare. In the spring each year, selected plots were pre-sown with mineral fertilizers at doses of 100 kg N, 35 kg P, 125 kg K, 12 kg Mg and 14 kg S per hectare. Organomineral fertilizer based on low-energy lignite was applied to the preceding crop (maize grown for silage) on two plots, in 1 and 5 t.ha−1 doses. Mineral fertilizers used in research significantly reduced the content of nitrogen, phosphorus, potassium, magnesium and sulphur in the dry matter of plants. The uptake of the nutrients reached the highest values for maize treated with NPKMgS + N1, NPKMgS + N2 and NPKMgS + N3. The agronomic efficiency (AE) of nitrogen, phosphorus, potassium, magnesium and sulphur, all of which were applied in the form of the polyfoska® fertilizer, M-MAKS (NPKMgS), potassium salt and urea, reached the highest values for plots treated with NPKMgS + N1 and NPKMgS + N2. In turn, the treatment of NPKMgS and NPKMgS + N3 with nitrogen, phosphorus, potassium, magnesium and sulphur resulted in the highest values of physiological efficiency (PE). Based on the three-year research carried out with the use of polyfoska® M-MAKS (NPKMgS), potassium salt and urea in the fertilization of maize grown for silage, it is possible to recommend the optimal dose of NPKMgS + N1 mineral fertilizers (100-35-125-12-14 pre-sowing, 20 kg top dressing N) and NPKMgS + N2 (pre-sowing 100-35-125-12-14, top dressing 40 kg N). The low-energy lignite applied to the preceding crop in doses of 1 t and 5 t at the NPKMgS + N1 and NPKMgS + N2 plots contributed to the achievement of the analyzed parameters (uptake, AE and AE) at a high level.

This investigation assessed the effects of special fertilizers on maize. The experiment was performed according to a randomized block design, with four replications in a 7 × 4 + 1 factorial scheme, representing seven sources (filter-cake-based organic compound, biochar-based organic compound, organic-mineral (OM) filter-cake, OM biochar, OM filter cake + humic substances (HS), mineral fertilizer with polymers, and conventional mineral) and four fertilizer levels based on the nitrogen (N) contents (60, 120, 180, and 240 kg/ha). An absolute control, without any fertilizer application, was used. At 60 days after sowing (DAS), the plant growth parameters, nutritional status, and residual nutrients in the soil were evaluated. The mineral fertilizer with polymers and OM filter-cake + HS showed better results for the dry matter of the shoot of the plant and plant height. When considering the leaf area, the OM filter-cake and OM filter-cake + HS fertilizers stood out. The accumulation of N and potassium (K) in the shoot of the plants was higher when the OM filter-cake + HS and mineral fertilizer with polymers were applied. With respect to the accumulated phosphorus (P), treatment with the OM filter-cake, OM filter-cake + HS, and mineral with polymers showed better results. On the other hand, for the analysis of P and residual K in the soil, the treatments based on filter-cake and biochar organic compost were better. Treatment with the OM filter-cake + HS and mineral with polymers stood out when considering the plant growth parameters and nutritional aspects of the maize crop.

In the cultivation of herbal plants, besides the size of the crop, the quality of obtained raw material is extremely important, which is proven not only by the appearance and taste, but also biological value. Factors that affect these parameters include plant nutrition. The main nutrient affecting the correct course of metabolic processes in a plant is potassium. To obtain high yield in terms of quantity and quality, the nutritional requirements of plants must be met. The aim of the study was to determine the effect of potassium nutrition on the quality of basil herb. The experiment was established in a two-factor scheme, in which the factors were: potassium dose (0.5, 1.0, 1.5 g K·dm–3) and the type of potassium fertilizer (KCl, K2SO4, KCl + K2SO4). The yield of basil plants was influenced by the dose and type of potassium fertilizers used (0.5 g K·dm–3 – 92.5; 1.0 g K – 67.3; 1.5 g K – 69.75 g·plant–1). The highest content of L-ascorbic acid was found in basil plants fed with the average potassium dose (65.9 mg·100 g–1 FW). The least nitrates (V) were contained in basil fertilized with KCl in the highest dose of K (63 mg·100 g–1 FW). No effect of the dose and type of potassium fertilizer on the content of phosphorus and sulfur in the plant material, was recorded. The content of Ca and Mg was influenced by both the potassium dose and the type of potassium fertilizer. The most of these components was revealed by plants fed with KCl, and with the increase of the dose, the content of both these mineral components decreased. Chlorine content in the herb increased with the applied potassium dose, the effect on the concentration of chlorine in the plant material was exerted by the type of potassium fertilizer applied – the highest concentration of this element was recorded. The content of macroelements in the substrate from basil cultivation was influenced by the dose and type of potassium fertilizers used. The best quality parameters of basil were obtained after application of 1.0 g K·dm–3 substrate in the form of KCl + K2SO4.

The influence of long-term application of potassium-deficient fertilizer system in the field crop rotation (winter wheat, corn, spring barley, soybeans) on podzolic heavy loam black earth of the Right-Bank Forest-Steppe of Ukraine on potassium content in plants, its costs for formation of one unit of the harvest was determined; potassium balance was calculated and the effectiveness of different doses of potassium fertilizers was comprehensively assessed. It was found that the potassium content in grains and seeds of agricultural crops under the influence of potassium fertilizers varies by no more than 8%, while in straw and stalks - by 10-24% depending on the variant of the experiment. It is shown that the non-grain part of the crop contains a significant part of potassium - 50-80% of economic removal depending on the crop. It is calculated that if it is left in the field for fertilizer in the variant of the experiment Basis + K80, it compensates for the consumption of potassium by 71%. By applying K40 and K80on the basis of applying N110P60 and leaving the non-commodity part of the crop in the field for fertilizer, the balance of potassium in the soil is formed positive with intensity of 111 and 212%, respectively. According to the index of complex assessment, which takes into account seven indicators: payback of 1 kg of mineral fertilizers; additionally conditionally net profit; net energy profit; humus balance and intensity of nitrogen, phosphorus and potassium balance, the best variant of the experiment is application of N110P60K40 per 1 ha of field crop rotation area. This indicates the possibility of a temporary reduction in the dose of potassium fertilizers in field crop rotation on podzolic heavyloam black earth in the Right-Bank Forest-Steppe of Ukraine

Full textAbstract:
Soil quality is one of the main factors that affect the growth and quality of tea (Camellia sinensis L.) plantations. The formation of the organo-mineral complex is one of the critical factors that influence the evolution of soil fertility. This study used chemical analyses and spectroscopy to study the effects of inorganic and organic fertilizer on the soil nutrients and organo-mineral complex in tea garden soil. SR-FTIR analysis revealed that clay minerals were connected as nuclei with the capacity to bind carbon, and that this interaction was aided by organic fertilization. Specifically, the O-H has the quickest reaction to aliphatic-C, next by Si-O, Fe-O, and Al-O in OM70. The soil pH of organic and inorganic fertilization treatments are obviously lower than the no fertilization (CK) treatment. Furthermore, OM70 and OM100 had notably higher pH values in fertilized soil. Organic fertilization (OM70) treatment significantly increased Soil organic matter (SOM), total nitrogen (TN), available phosphorous, potassium (AP, AK), as well as the concentration of total and exchangeable Ca2+ and Mg2+ in soils when compared to no fertilization (CK) and inorganic fertilization (NPK). Together, these results can provide the scientific theoretical basis for the study on the understanding of the sequestration of SOM and confirmed the feasibility of organic fertilization in improving soil fertility and supporting organo-mineral interactions, thereby making a contribution to carbon storage in tea plantation ecosystems.

Carbon dioxide (CO2) is an important greenhouse gas. CO2emission from different long-term fertilized black soils was investigated by incubation experiment at soil water content of 70% water holding capacity. Maximal CO2flux was observed at the beginning of 24-h and 48-h incubation after the rewetting of dry soil. Combined fertilizer nitrogen (N), phosphorus (P) with manure (M) emitted the highest CO2-C, was up to 175 mg kg-1. Compared to zero fertilization (CK), fertilizers application increased CO2emission (P<0.05). Single fertilization N, P and potassium (K) increased CO2emission 19%, 43% and 22%, respectively. Combined two-way or three-way fertilizer N, P and K also increased CO2emission. Based on mineral fertilization, additional organic manure application furthered CO2emission. Two-way fertilizers (NP, NK and PK) application with organic manure increased CO2emission at the percentage of 398, 13.8 and 29.1, respectively (P<0.05). Although organic manure application ameliorated soil chemical, physical and biological conditions, organic manure fertilization increasing CO2emission should be considered in agricultural practice.

Objective. To evaluate the influence of different fertilizer systems in combination with microbial preparations on the change of nutritional regime of sod-podzolic soil and the yield of crops of short-term crop rotation in the Polissia region. Methods. Fields — stationary experiment, laboratory, mathematical and statistical. Results. On the basis of studies conducted in a long-term stationary experiment on sod-podzolic soil, analysis and determination of dependence between the content of available compounds of nitrogen, phosphorus, potassium on fertilizer systems and microbial preparations was performed. It was found that the highest nutrient reserves in the soil were in the organo-mineral fertilizer system “manure + green manure + NPK” in combination with microbial preparations: the content of mineral compounds of nitrogen — 82.32 kg/ha, available phosphorus — 223 mg/kg of soil, and exchangeable potassium — 122 mg/kg, which is 1.8, 1.4 and 1.6 times higher than the parameter of the mineral fertilizer system, respectively. At the same time, due to the inoculation of seeds nitrogen reserves in the soil can increase up to 26 %. The application of the fertilizer system “manure + green manure + NPK” provides an optimal level of root nutrition of crops of short-term crop rotation and, as a consequence, the highest productivity of crops, which amounted to: winter rye — 5.2 FU (fodder units), potatoes — 7.7 FU, oats — 3.3, lupine — 3.8 FU on background without inoculation and 5.7, 8.3, 3.9 and 4.4 FU, respectively, when microbial preparations were applied. The increase due to inoculation with this fertilizer system amounted to 0.5 fodder units (FU) for winter rye, 0.5 FU for potatoes, and 0.6 FU for oats, and 0.6 FU for lupine. Conclusion. The nutrient regime of sod-podzolic soil depends on the use of various fertilizer systems in combination with microbial preparations. Organic-mineral fertilizer system “manure + green manure + NPK” under the use of microbial preparations is most effective for growing crops on sod-podzolic soil in short-term crop rotation. This combined fertilizer system contributes to the greatest accumulation of nutrient reserves: nitrogen mineral compounds — 82.3 kg/ha, available phosphorus — 220 mg/kg of soil and exchangeable potassium — 122 mg/kg.

<p>Algae have been explored as inorganic nutrient sources, human and animal food and biochemical products. Several beaches in the northeastern state of Alagoas, Brazil, frequently experience large amounts of algal drifts, representing a huge amount of biomass that could be used as an organic fertilizer for coastal farmers. The purpose of this study was to observe the growth and development of lettuce grown using algal with organic fertilizers. The lettuce was grown in the following conditions: controlled, soil neither algal powder nor cattle manure, soil plus 5% of algal powder, and soil plus 5% of cattle manure. The lettuce plantlets were transferred to a substrate and harvested with after 60 days. The fresh and dry mass, shoot and root length of the lettuce plants, and the mineral nutrient content of the algae fertilizer were evaluated as parameters Algae fertilizers have low levels of phosphorus and but have suitable levels of other mineral nutrients when compared to other organic fertilizers. Algal fertilizers induced a similar growth response in lettuce plants compared to cattle manure. Overall, this data lets us conclude that algal drifts, with the addition of phosphorus and potassium, might be a good resource as an organic fertilizer.</p><p> </p>

The article presents the results of three-year (2017-2019) field studies on changes in agrochemical characteristics of soil and formation of productivity of birdsfoot trefoil and timothy grass mixture in dependence of the liming (hydrolytic acidity 0.25) and application of mineral fertilizers, phosphorite meal in particular. The soil is sod-podzolic, medium loamy, strongly acidic, with intermediate concentration of mobile phosphorous and metabolizable potassium, humus content is 1.9 %, and mobile aluminum – from 4.27 to 5.24 mg/kg of soil. It has been established that application of finely ground lime at a dose of 3 tons per hectare prior to sowing of birdsfoot trefoil and timothy grass mixture decreased soil acidity in the layer of 0-10 cm from 4.2 to 5.6 pH units by next autumn. Application of phosphorite meal (1t/ha) led to an increase in the concentration of mobile phosphorous in the layer of 0-10 cm by 135-163 %. The highest productivity of birdsfoot trefoil and timothy mixture during 3 years was obtained by means of combined application of lime and mineral fertilizers, and for 3 years on the average the yield of metabolic energy exceeded 50 GJ/ha, which is over 35 % higher than in the control variant without fertilizers. The use of mineral fertilizers increased grass mixture productivity only during the first two years. The applied dosage of phosphorite meal (1t/ha) promoted the increase in grass productivity on strongly acidic soil only in the year of sowing. Additional treatment with ammonium nitrate (N30) together with phosphorous and potassium fertilizers (Р60К60), as well as potassium chloride (К60) with phosphorite meal did not result in significant rise in metabolizable energy yield.

Trembling aspen seedling establishment, growth and response to fertilization on contrasting soils used in oil sands reclamation. Can. J. Soil Sci. 92: 143–151. Trembling aspen (Populus tremuloides) is an important tree species for land reclamation. This study determined trembling aspen germination, establishment, initial growth and response to fertilizer on contrasting oil sands reclamation soils. In a greenhouse, eight soils varying in total nitrogen and available phosphorus were treated with no fertilizer (control), phosphorus and potassium (PK), nitrogen (N) and all three (NPK). Soil had the greatest impact on aspen growth when no fertilizer was applied with the best growth occurring on organic-mineral material soils where growth was positively correlated with extractable and foliar potassium but not to nitrogen or phosphorus. With PK and N fertilizer, growth increases were positively correlated with foliar phosphorus concentrations of the corresponding controls. NPK fertilizer caused greater growth, bud set and root:leaf mass ratio compared with PK or N fertilizer. Soil type had little impact on germination and establishment, indicating natural aspen seedlings can potentially regenerate on all of these soils. In oil sands mining reclamation where these soils are used as surface materials, organic-mineral mixes had the greatest potential without fertilizer. With fertilizer, NPK provided maximum growth and developmental benefits.

The mineral fertilizing and the supply of water seem to influence the content of lycopene in the fruits of tomato, thus it is crucial to elucidate the ideal levels of fertilizers and the adequate management of irrigation for this crop. Hence, the study had an objective to evaluate the efficiency of different levels of mineral fertilizing and the effect of irrigation management on the productivity as well as on the lycopene content in the fruits of tomato. For this, two experiments in Winter/Spring and Summer/Autumn were carried out. The treatments consisted of the combination of different levels of mineral fertilizersing with nitrogen, phosphorous, and potassium along with two levels of irrigation. The productivity of fruits, the production of large fruits, the lycopene content, and the efficiency in the use of nutrients, were evaluated. With the application of 120% of the recommended dose of fertilizing, the productivity of large fruits was maximum. The efficiency in the use of nitrogen, phosphorous, and potassium was maximum with the application of 120, 121 and 50% of the recommended dose of fertilizing, respectively, and 100% of the irrigation depth. The maximum content of lycopene was obtained, by applying 200% of the fertilizing dose and 50% of the irrigation depth. The best combination for the production of large fruits, higher lycopene content, and higher efficiency in the use of nitrogen, phosphorous, and potassium, was the application of 120% of the dosage of fertilizing and 100% of the irrigation depth.

The aim of this study was to evaluate the physiological and growth responses of watermelon under application of NPK rates using different proportions of mineral and organic fertilizers. The experiment was taken place in an area located at the Federal University of Campina Grande (UFCG), Campus Pombal - PB (6º48'16'' S and 37º49'15'' W), during the period from June to September 2013. The treatments consisted of three nutrient concentrations of N, P and K (50, 100 and 150% of NPK recommendation for watermelon) and five proportions of mineral and organic fertilizer (100/0, 75/25, 50/50, 25/75 to 0/100). The design was a randomized block in factorial scheme 3 x 5, with four replications. The amount of 100 % was the corresponding NPK 120 kg ha-1, respectively, for N, P and K. They were evaluated: gas exchange, leaf dry matter, stem, fruit and leaf area. The concentration of 150 % of the recommended NPK to the culture of watermelon was the most effective in increasing the physiological characteristics and dry matter accumulation in stem, leaf, fruit, and leaf area. The combined application of mineral and organic fertilizer provides equivalent photosynthetic rate isolated application of mineral fertilizer with an 50/50 ratio the most effective for this variable. The proportions 75/25 and 50/50 were the most efficient in dry matter accumulation in watermelon.

The purpose of the research is to assess the humus state and functioning of the soil absorbing complex of leached chernozem during the rotation period of the six–field grain crop rotation. Traditional methods of soil research were used in field long-term experience. The medium and high rates of the mineral fertilizers of nitrogen, phosphorus, potassium, as well as the organic fertilizers (litter, liquid manure, straw) and their combinations with mineral solid fertilizers were used. The application of the mineral fertilizers for a circle of the crop rotation contributed to an increase in all types of soil acidity. The use of the litter manure and straw significantly reduced the indicators of an active, metabolic and hydrolytic acidity, respectively, by 6.8-1.7, 15.2-13.0, and 18.4-8.2% relative to the control. The joint application of the organic and mineral fertilizers slows down the rate of acidification of the soil, but does not eliminate them. The use of the litter manure and its combination with a mineral fertilizer caused an increase in the carbon content of humus, respectively, by 3.9 and 11.6%. The use of the straw in a combination with the mineral fertilizer and liquid manure increased the carbon content of humus, respectively, by 1.4 and 14.5% relative to the control. The degree of humification with increasing rates of the mineral fertilizers decreased from 24.2 to 22.3, and with the use of the organic fertilizers increased from 22.3 to 25.2.

Mineral nutrition improvement contributed signifcantly to spring triticale grain yield. On average, during the two years of research, the use of 30–210 kg/ha of active ingredient of nitrogen fertilizers increased it to 6.50–8.36 t/ha or by 14–46 % compared to unfertilized plots (5.71 t/ha). The stability index of yield formation was high – 0.92–0.95. Weather conditions in research years were different. The precipitation level in April – June 2014 made 442.7 mm, and in 2015 – 87.5 mm. In 2014, the application of N30–210 signifcantly increased the grain yield – by 0.81–2.66 t/ha, and in 2015 – by 0.77–2.64 t/ha compared to no fertilizer variant. It is worth noting that the use of phosphorus–potassium fertilizers provided 0.30–0.32 t/ha. The application of 30–210 kg/ha of active ingredient of nitrogen fertilizers increased the protein content in spring triticale grain. During the two years of research, it increased, on average, from 13.7% in no fertilizer variant to 13.8–15.4 % or 1–12 %. The use of phosphorus– potassium fertilizers did not change this indicator. The use of high doses of nitrogen fertilizers (120–210 kg/ha) slightly reduced the stability index of protein content in the grain to 0.87–0.90. In terms of protein yield in triticale grain yield, variants with nitrogen fertilizers have signifcant advantage of unfertilized plots with the stability index of 0.92– 0.99. On average, during the two years of research, this indicator increased by 115–506 kg/ha or 1.1–1.6 times (894–1285 kg/ha) compared to no fertilizer variant. The use of phosphorus–potassium fertilizers increased protein yield to 818 kg/ha or 5 %. Gluten content varied greatly from the use of nitrogen fertilizers. On average, over two years of research, its content increased from 18.7% in no fertilizer variant to 20.4–26.4 % or 9–41 %. Stability index in this fertilizer scenario increased from 0.76 to 0.91. The use of phosphorus–potassium fertilizers had the least effect on gluten content – 19.3 %. In the conditions of the Right–Bank Forest–Steppe in the fertilizer system of spring triticale varieties of Kharkiv Khlibodar type the dose of nitrogen fertilizers is 60–90 kg/ha. In this scenario, the yield is 6.80–7.90 t/ha, protein content – 14.0–14.5 %, gluten content – 23.6– 25.0 %. The grain corresponds to the frst quality class according to SSTU 4762: 2007. Triticale.

The article presents the results of liming and fertilization influence on the content and removal of nitrogen, phosphorus and potassium by maize on sod-podzolic sandy soil of Western Polissia. It was determined that the content of the main nutrients varied within 1.63–1.90 and 0.77–0.86 % for nitrogen, 0.51–0.59 and 0.32–0.41 % for phosphorus, 0.31–0.45 and 1.24–1.32 % for potassium respectively in the main and by-products. The highest accumulation NPK data were noted in the variant with application a 1.0 dose by hydrolytic acidity (Ha) of dolomite flour and N120P90K120 with addition of S40 and micronutrient fertilizer Nutrivant Plus Cereals (2 kg/ha). The total uptake of elements mainly depended on the combination of fertilizer components and liming doses. The maximum removal data were established for variants with a 1.0 dose by Ha of dolomite flour, norms of mineral fertilizers N120P90K120 and the addition of S40, as well as S40 and micronutrients fertilizer Nutrivant Plus Cereals (2 kg/ha). These data 1.8–2.3 times for the main product and 2.0–2.3 times for by-products exceeded the control. A more stable indicator that will make it possible to adjust the crop nutrition system is the removal of nutrients per unit of the main and the corresponding amount of by-products. It was found that with liming and fertilization, the consumption of nitrogen, phosphorus and potassium by corn plants and the normative removal rate increase. In the experiment, high values of removal of 33.5 and 32.6 kg/t of nitrogen, 12.3 and 12.4 kg/t of phosphorus, 26.9 and 24.1 kg/t of potassium were obtained with the integrated application a 1.0 Ha dose by Ha of dolomite flour, N120P90K120 with the addition of sulfur, as well as sulfur and trace elements. Key words: corn, liming, fertilizers, productivity, nitrogen, phosphorus, potassium, elements content, nutrients removal.

Full textAbstract:
The research purpose is to study the effect of systematic application of various doses of mineral fertilizers on productivity, grain quality, value of spring barley productivity elements, determine an optimal doses of nitrogen, phosphorus and potassium in the arid conditions of the Middle Volga region. Improving nutrition with the use of fertilizers contributed to an increase in productivity values. The average yield was 0.18–0.76 t/ha. The use of maximum doses of nitrogen, phosphorus and potassium did not increase productivity in arid conditions. Nitrogen plays a leading role in increasing barley productivity. The agronomic effectiveness of fertilizers depended on the doses of active substances. An increase was 2.1–5.8 kg of barley grain per 1 kg of active substances. The most stable increase was observed when applying N60Р0-60К0-30. Rational doses are as follows: nitrogen 60–90 kg a.e./ha when applying P60K30, phosphorus 30–60 kg a.e./ha when applying N60K30, potassium 30 kg a.e./ha when applying N60Р60. The best option is N60Р0-60К0-30.

In our pot experiment, the impact of a bacterial fertilizer, Bactofil® A10 and a mineral fertilizer Ca(NO3)2 applied in different rates was studied on some soil chemical and microbiological characteristics of a humic sandy soil (Pallag). Perennial rye-grass (Lolium perenne L.) was used as a test-plant. Samples were collected four and eight weeks after sowing in each year. The experiment was set up in 2007-2009 in the greenhouse ofthe UD CASE Department of Agrochemistry and Soil Science. The available (AL-extractable) nutrient contents of soil, among the microbial parameters the total number of bacteria, the number of microscopic fungi, cellulose-decomposing and nitrifying bacteria, the sacharase and urease enzyme activity, as well as the soil respiration rate were measured.Statistical analyses were made by means of the measurements deviation, LSD values at the P=0.05 level and correlation coefficients were calculated. Results of our experiment were summarised as follows:− The readily available nutrient content of humic sandy soil increased as affected by the treatments, in case of the available (AL-extractable) phosphorus and potassium content the higher value was measured in high-dosage artificial fertilizer treatment.− The treatments had also positive effect on several soil microbial parameters studied. The higher-dosage mineral fertilizer treatments had a beneficial effect on the total number of bacteria, cellulose-decomposing and nitrifying bacteria. No significant differences were obtained between the effect of treatment in case of the total-number of bacteria, the number of microscopic fungi and nitrifying bacteria.− On the sacharase enzyme activity the artificial fertiliser treatments proved to be unambiguously stimulating, the urease activity significantly increased on the effect of the lower-dosage Ca(NO3)2 artificial fertilizer treatment. − The soil respiration increased in all treatments in related to the amounts applied, significantly increased in the highest rate of Ca(NO3)2 fertilizer addition. − Some medium and tight positive correlations were observed between the soil chemical and microbiological parameters studied in case of both nutrient sources. Summarizing our results, it was established that the organic and all the mineral fertilizer treatments had beneficial effects on the major soil characteristics from the aspect of nutrient supply. In majority of the examined soil parameters (AL-extractable phosphorus- and potassium, total number of bacteria, number of cellulose-decomposing and nitrifying bacteria, activity of sacharase enzyme) the high rate of Ca(NO3)2 mineral fertilizer treatment proved to be more stimulating, but at the same time the high rate bacterium fertilizer resulted in significant increases inthe nitrate-N content, the AL-potassium content of soil, the total number of bacteria, the number of cellulose-decomposing and nitrifying bacteria and the urease enyme activity. Our examinations showed that the mineral fertilizer treatments proved to be more stimulating on most of the soil parameters studied but according to our results, it was established that Bactofil is efficiently applicable in the maintenance of soil fertility and the combined application ofmineral fertilizer and bacterium fertilizer may be a favourable opportunity – also in aspect of the environmental protection – in maintaining soil fertility.
