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:
Av samtliga globala processer som reglerar jordsystemet är de biogeokemiska flödena av kväve (N) och fosfor (P) mest påverkade av mänskliga aktiviteter. Inerta former av N och P omvandlas till reaktiva former som sprids i miljön, där de orsakar eutrofiering och påverkar marina ekosystem negativt. Majoriteten av de reaktiva N- och P-formerna används för framställningen av mineralgödsel. Ett alternativt sätt att producera gödsel är att återvinna näringsämnena i avloppet. En teknik som återvinner näringsämnen i urin är basisk urintorkning. Teknologin stabiliserar urea med ett basiskt torkningsmedium och koncentrerar näringsämnena genom att evaporera vattnet i urinen. Slutprodukten är ett torrt gödsel i pulverform. I det här projektet testades urintorkningsteknologin för första gången i ett fältförsök. Ett system för urintorkning med kapacitet att förånga 40 kg urin dygn-1 m-2 konstruerades och integrerades i ett befintligt torrt sanitetssystem för användning under en period på tre månader. I projektet utvärderades 13 dygn av de 3 månaderna. Resultaten visade att 24 kg urin tillfördes systemet och att systemet kunde upprätthålla en kontinuerlig torkning av urinen. Efter torkningen återvanns majoriteten (97 %) av N i slutprodukten. På grund av att den tillförda mängden urin var liten blev växtnäringshalterna i slutprodukten och i torrsubstansen (TS) av slutprodukten låga. Systemet hade emellertid potential att torka mycket större kvantiteter urin. Om systemets fulla potential hade använts, det vill säga att torka 40 kg urin dygn-1 m-2, så hade särskilt N- och P-halterna ökat avsevärt. N-halterna hade även ökat ytterligare om torkningen hade utförts vid en lägre temperatur. Systemets energiförbrukning var hög, eftersom systemet hade en kontinuerlig energikonsumtion och även komponenter med hög effekt. I jämförelse med den konventionella avloppsvattenreningen och produktionen av mineralgödsel har systemet en hög energikonsumtion, men i jämförelse med en förbränningstoalett är systemets energiförbrukning likvärdig. För att minska energiförbrukningen kunde reglertekniska åtgärder utföras så att systemets energitillförsel upphör när systemet inte används. Systemets energiförbrukning får även ställas i relation till de problem som dagens system för livsmedelsproduktion och sanitet medför. Till skillnad från nämnda system möjliggör urintorkningsteknologin besparing av dricksvattenresurser, ett slutet kretslopp av näringsämnen och en minskad påverkan på miljön.Of all global processes that regulate the earth system, the biogeochemical flows ofnitrogen (N) and phosphorus (P) are the most affected by human activities. Inert forms of N and P are converted into reactive forms that are dispersed in the environment, causing eutrophication and affecting marine ecosystems. The majority of the reactive N and P are used for the production of mineral fertilizers. An alternative way of producing fertilizers is to recycle nutrients from waste water. A technology that reuses nutrients in urine is alkaline urine drying. The technology stabilizes urea with an alkaline drying medium and concentrates the nutrients by evaporating the water in urine. The end-product is a dry fertilizer in powder form. In this master project, the alkaline urine drying technology was tested for the first time in field conditions. A system for urine drying with the capacity to evaporate 40 kg of urine day-1 m-2 was constructed and integrated into an existing dry sanitation system for use over a period of three months. The master project evaluated the system for 13 days of the 3 months. The results showed that 24 kg of urine was collected in the system, significantly less than what the system had been designed to dry. Furthermore, the results showed that the system functioned smoothly recovering 97 % of the urine-N in the end-product. The nutrient content in the end-product and the dry matter of the end-product was low due to the low amount of urine that was collected. However, the system had the potential to dry much larger quantities of urine. If the system would have been operated to function at full potential (drying 40 kg of urine day-1 m-2) the N- and P-content in the end-product would be much higher than that observed during the 13 days. Furthermore, the system if operated at lower temperatures has the potential to recover more N. The system’s energy consumption was high, as the system had a continuous energy consumption. In comparison with the conventional waste water treatment and the production of mineral fertilizers, the system has a high energy consumption, but compared to an incineration toilet, the system’s energy consumption is equivalent. In order to reduce the energy consumption, automatic control could be implemented so that the energy is switched off when the system is not used. The system’s energy consumption may also be set in relation to the problems that today’s systems for food production and sanitation entail. Unlike the aforementioned systems, the urine dehydration technology does not consume drinking water, it enables recycling of nutrients as well as a reduced impact on aquatic life.

No estado do Espírito Santo, estima-se que existem pouco mais de 226 mil cabeça de suínos, gerando cerca de 730.000 m³ de dejetos ricos em nutriente anualmente. Dessa forma, partindo do pressuposto que a aplicação da Água Residuária de Suinocultura (ARS) pode promover alterações nos teores de potássio do solo, promovendo incremento desse nutriente, bem como propiciar aumento da produção de massa seca do Panicum maximum cv. Mombaça, sem que haja desbalanceamento nutricional da planta, objetivou-se avaliar os teores de potássio no solo e na planta, bem como a produção de massa seca do Capim Mombaça (Panicum maximum cv. Mombaça) decorrentes de diferentes doses de ARS em comparação com a adução mineral. Esta pesquisa foi realizada em uma propriedade rural, localizada no município de Jerônimo Monteiro – ES. Para o K e a relação K/CTC, utilizou-se o esquema de parcelas subsubdivididas com três repetições. As parcelas receberam cinco tratamentos sendo: adubação mineral (200 kg ha-1 K) via Cloreto de Potásio; e doses de ARS 50, 100, 150 e 200, equivalentes a 100, 200, 300 e 400 kg ha-1 K, calculados a partir da recomendação agronômica. Nas subparcelas, teve-se às profundidades do solo, sendo: 0 a 10; 10 a 20; 20 a 40 e 40 a 60 centímetros. Nas subsubparcelas, a situação representada pelo tempo antes da aplicação da ARS foi denominada AAARS, e dez dias após cada aplicação da ARS, denominada DAARS. Para a Massa Seca e o teor de K na planta, teve-se um esquema de parcelas subdivididas com três repetições. As parcelas receberam os tratamentos: adubação mineral e doses de ARS 50, 100, 150 e 200% da dosagem recomendada de potássio. As subparcelas foram os períodos de avaliação das aplicações da ARS aos dias 10, 130, 210 e 270 decorridos do início do experimento. Depois dos resultados obtidos, procedeu-se a análise estatística por meio de análise de variância adotando 5% significância F, sendo realizado o contraste entre os valores médios obtidos para adubação mineral e a ARS ao nível de 5 % de probabilidade, pelo teste de Tukey. Posteriormente, para as variáveis quantitativas foi realizada a análise de regressão a 5% de significância, sendo os modelos foram escolhidos pela utilização o teste t de Student, e pelos coeficientes de determinação R2, utilizando-se o software SAEG. Verificou-se que, mesmo com a aplicação de doses de K superior à recomendação agronômica através da ARS, ocorreu a redução linear dos teores de K no perfil solo, assim como ocorre o acréscimo linear desses teores com o aumento da dose. A aplicação ARS mostrou-se mais eficiente para incrementar K no solo, quando comparada à Adubação Mineral. A dose que se mostrou mais eficiente na manutenção dos teores K no solo é ARS 150 %. A maior produção de biomassa deu-se na dose 50%, todavia culminando com os menores teores de K na planta do capim Mombaça, e os maiores teores na planta foram obtidos nas maiores doses de ARS. Verifica-se que os atributos químicos do solo são influenciados pela aplicação de ARS, o que denota a necessidade de periodicidade na avaliação desses atributos em áreas com aplicação contínua de ARS.
In Espírito Santo state, it is estimated that there are just over 226 000 head of pigs, therefore, these generate about 730.000m³ nutrient-rich waste annually. Thus, assuming that the application of the swine wastewater can promote changes in the potassium soil, promoting increment this nutrient as well as provide increased dry matter yield of Panicum maximum cv. Mombasa, without nutritional unbalance the plant, it was aimed to evaluate the levels of potassium in the soil and plant, and the dry mass of Mombasa Grass (Panicum maximum cv. Mombasa) resulting from different doses of ARS compared to mineral adduction. This research was conducted in a rural property located in the municipality of Jeronimo Monteiro - ES. For K and K/CEC was used a scheme split-split-plot portion with three replications. The plots received five treatments being: mineral fertilizer (200 kg ha-1 K) via potassium chloride; ARS and doses of 50, 100, 150 and 200, corresponding to 100, 200, 300 and 400 kg ha-1 K, calculated from the agronomic recommendation. Subplots, it was taken to the depths of the soil, being: 0-10; 10 to 20; 20 to 40 and 40 to 60 centimeters. In the sub-subplots, the situation represented by time before the application of ARS was named AAARS, and ten days after each application of ARS, called DAARS. For Dry mass and K content in the plant, had become a split plot arrangement with three replications. The plots received treatments: mineral fertilizer and doses of ARS 50, 100, 150 and 200% of the recommended dosage of potassium. The subplots periods of evaluation of the applications of ARS 10 days, 130, 210 and 270 elapsed from the beginning of the experiment. After the results, it was proceeded to statistical analysis using analysis of variance adopting 5% significance F, the contrast between the mean values obtained for mineral fertilizer and the ARS at 5% probability being performed by Tukey test. Subsequently, for quantitative variables regression analysis the 5% significance level was conducted, and the models were chosen by using the Student t test, and the coefficient of determination R2, using the SAEG software. It was found that, even with the application of higher doses of K recommendation the agronomic via ARS occurred linear reducing of the content K in the soil profile as well as linear increase these levels with increasing dose occurs. The ARS application was more efficient to increase soil K compared to mineral fertilization. The more effective dose in maintaining levels of K in the soil was ARS 150%.The highest biomass yield was given at a dose 50%, however culminating with the lowest levels of K in the plant grass Mombasa, and the highest levels in the plant were obtained at higher doses of ARS. It appears that the soil chemical properties are influenced by the application of ARS, which indicates the need for periodicity in the evaluation of these attributes in areas with continuous application of ARS.

Full textAbstract:
Abstract Low and unreliable rainfall, along with poor soil health, is a main constraint to maize production in the semi-arid parts of Kenya that account for over 79% of the country's land area. In the vast county of Laikipia, farmers continue to plant maize despite the predominantly low quantities of precipitation. Participatory farmer experimentation with Conservation Agriculture (CA) was undertaken for six consecutive growing seasons between July 2013 and December 2016 to determine the effectiveness of CA as a method of improving soil properties and enhancing maize yields with the limited rainfall quantities received in these parts of Kenya. The main CA practices tested include chisel tine furrow opening (ripping) and live legume (Lablab purpureus) cover crop, as well as maize stover mulches, all implemented under varying inorganic fertilizer rates. The research was done across 12 administrative locations of Laikipia County where soils are mainly Phaeozems and Vertisols with a clay-loam texture. The research design used was researcher-designed and farmer-managed. In each of the 12 trial sites, participatory farmers' assessments and field days were carried out as a way of outreach to the bigger farming communities around the trial sites. The research findings obtained demonstrated that the use of CA impacts positively on soil properties and is a viable practice for enhancing maize yields in these moisture deficit-prone parts of the country. Soil chemical analysis assessment results showed that CA impacted positively on a number of soil mineral components including organic carbon, total nitrogen, phosphorus, potassium, calcium and pH. Midseason chlorophyll content assessment of the maize crop showed that there was good response to fertilizer application, as well as to mulching with crop residues for soil cover. Maize grain yield data also showed that the use of a CA package comprising chisel tine ripping combined with mulching by plant residues and use of mineral fertilizer resulted in a two- to threefold increase in grain yields above the farmer practice control. Mean maize grain yield in farmer practice plots was 1067 kg ha-1 compared with the CA-treated plot with mineral fertilization that yielded 2192 kg ha-1.

Full textAbstract:
The widespread practices of viniculture (the study of production of grapes for wine) and oenology (the study of winemaking) affirm the generalization that grapevines have fewer problems with mineral deficiency than many other crops. Only occasionally is the addition of iron (Fe), phosphorus (P), magnesium (Mg), and manganese (Mn) supplements to the soil needed. Addition of potassium (K), zinc (Zn), and boron (B) to the soil is more common. And, of course, nitrogen (N) is critical for the production of proteins. Over the years, various transition metals (metals in groups three through twelve [3– 12] of the periodic table, Appendix 1) have been shown to be generally important. These groups include iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn), and copper (Cu). Many metals are bound to organic molecules that are important for life. Some of the metals, such as copper (Cu) and iron (Fe), are important in electron transport while others, including manganese (Mn) and iron (Fe), inhibit reactive oxygen (O) species (ROSs) that can destroy cells. Metals serve both to cause some reactions to speed up, called positive catalysis while caus¬ing others (e.g., unwanted oxidation) to slow down (negative catalysis). It is not uncommon to add nitrogen (N), in the form of ammonium salts such as ammonium nitrate (NH4NO3), as fertilizer to the soil in which the vines are growing. It is also common to increase the nitrogen (N) content in the soil by planting legumes (legumes have roots that are frequently colonized by nitrogen-fixing bacteria). Nitrogen- fixing bacteria convert atmospheric nitrogen (N2), which plants cannot use, to forms, such as ammonia (NH3) or its equivalent, capable of absorption by plants. Nitrogen, used in plant proteins, tends to remain in the soil after harvest or decomposition. With sufficient nitrogen present in the soil the growth cycle can begin again in the following season without adding too much fertilizer. In a more general sense, however, it is clear (as mentioned earlier) that the soil must be capable of good drainage so the sub-soil parts of the plant do not rot and it must be loose enough to permit oxygen to be available to the growing roots.

Soil testing can be a valuable method to help turfgrass managers make fertilizer decisions and choosing the most appropriate soil test extractant is key. This depends on soil properties and the availability of correlation data for turfgrass species in the desired region. This chapter describes common extracts and demonstrates their efficacy for phosphorous and potassium extraction with three soil samples from the North American Proficiency Testing program (http://www.naptprogram.org/) administered by the Soil Science Society of America. Fertilizer recommendations were made based on regional sufficiency levels from university soil-testing laboratories and the Minimum Levels for Sustainable Nutrition (MLSN) guidelines from the Asian Turfgrass Center and PACE Turf. Sufficiency Levels for Available Nutrients (SLAN) or MLSN guidelines are most appropriate for deciding how to fertilize turf. However, recommendations based on an inappropriate extractant, calibration, saturated paste extraction, or ideal ratios or of major exchangeable cations (i.e., Basic Cation Saturation Ratio) are inappropriate.

Metals, inorganic compounds and their elements that act as cofactors for enzymes that play an essential role in various biological processes constitute mineral nutrients. Their primary source is soil and enters the climax consumers in food chain through plants as they contain most minerals that are essential for humans. They are required in small and precise amounts according to their requirement they were classified as Major (phosphorous (P), potassium (K)), Secondary (calcium (Ca), magnesium (Mg), sulphur (S)), Minor/trace/rare (Boron (B), chlorine (Cl), chromium (Cr), fluoride(F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se), sodium (Na), vanadium (V) and zinc (Zn)). The daily requirement of minerals for individuals for effective biological function inside the cell is known as recommended dietary allowance (RDA) that varies for element. The daily requirement of major element is up to 10 g/d, whereas secondary and micro minerals was 400 - 1500 mg/d and 45 μg/d - 11 mg/d, respectively. Meats, vegetables, fruits, grains contains high amount of minerals that protect humans from mineral deficiencies. Some of the mineral deficiencies include ageing, cancer, hair loss etc. The key for these root problems include supplementation of healthy foods rich in minerals and understanding the importance of food by nutrition education, practice of physical activity, and about food habits. A detailed understanding of each mineral and their biological importance through mechanism of action studied in detail to overcome their deficiencies.

Full textAbstract:
Durum wheat (Triticum durum Desf.) grain is the main raw material for the production of high-quality pasta and cereal products. The research was conducted at Uman National University of Horticulture (Ukraine) in a long-term stationary experiment, founded in 2011. The aim of the work was to study the impact of long-term use of various fertilization systems (with incomplete return of nitrogen, phosphorus and potash fertilizers) on the yield and quality of durum winter wheat grain. The long-term application of nitrogen, nitrogen-potassium, nitrogen-phosphorus and nitrogen-phosphorus-potassium systems in the field crop rotation has a strong impact on the formation of durum winter wheat yield. Long-term use of N150P60K80 increases it from 3.6 t ha-1 up to 4.9 t ha-1 (p≤0.05). The use of half a dose of complete mineral fertilizer provides 4.5 t ha-1 (p≤0.05). Variants with incomplete return of phosphoruspotassium fertilizers, as well as paired combinations with a nitrogen component, provide the formation of 4.6–4.8 t ha-1 grains. Nitrogen fertilization systems increase grain yield to 4.2–4.5 t ha-1 depending on the fertilizer dose. It should be noted that durum winter wheat responds well to the use of nitrogen fertilizers, as the protein content increases from 13.3 to 14.8–15.9 % (p≤0.05), and the gluten content from 28.0 to 31.1–33.4% (p≤0.05) depending on the fertilization system. The protein content was most affected by the application of nitrogen component from complete mineral fertilizer.

This article describes the effect of various doses of mineral fertilizers with trace elements based on pure silicon – “Nanosilicon” on corn plants. It is important to point out that new and perfect varieties are created every year, although, without the use of fertilizers, they will not be able to give the maximum yield. The main nutrients are nitrogen, phosphorus and potassium, often forgetting silicon, even though it also plays an important role in growth and development, as well as in the crop yield; in this research, we studied corn in the central zone of the Krasnodar Territory. Fertilizer “Nanosilicon” increased the height of corn plants by an average of 17 cm or 9.9 %; wet weight by 100.4 g/plant or 17.5 %; yield, as one of the main indicators, by 7.68 kg/ha or 15.4 %.

Corn plays a leading role in providing the livestock industry with green and juicy feeds. To increase the yield and quality of green mass, the use of nitrogen fertilizers is of great importance [1]. In a field experiment on sod-podzolic soils in the conditions of the Minsk region, on the basis of LLC "Gastellovskoye" of the Minsk district, the influence of nitrogen fertilizer Life Force Humic N on the yield and quality of the green mass of the Dolphin corn hybrid was studied. Water-soluble nitrogen fertilizer Life Force Humic N on corn crops was used in phases: 4–6 leaves, sweeping of the panicle and the beginning of flowering of the crop. The content of the main elements of nutrition (nitrogen, phosphorus, potassium) in the green mass of corn under the influence of the fertilizer Life Force Humic N varied within the error of the experiment and at the level with the use of control. No significant changes in the protein content depending on the use of equivalent doses of mineral nitrogen (control) and Life Force Humic N fertilizer have been established. The maximum protein content (5.6–5.7%) was noted both in the variant with the use of top dressing with standard nitrogen fertilizer and with the Life Force Humic N. fertilizer. When cultivating corn for green mass, the use of three-fold non-root treatment of crops with liquid water-soluble nitrogen fertilizer Life Force Humic N increased the yield of the green mass of the crop by 31 c / ha. When cultivating corn for green mass, the use of non-root treatments with Life Force Humic N fertilizer at a dose of 1 l/ ha is recommended.

The paper presents the basic characteristics and prerequisites for improving the production of butter lettuce "Shangore" in order to obtain guidelines in the application of lettuce cultivation technology, stable yield, increased nutritional value and uniform quality. Fertilization treatments in the experiment included: phosphate-based mineral fertilizer, humic acid-based organic fertilizer, and liquid organic-mineral fertilizer. The results of this research indicate that the average value of lettuce yield was the highest in the application of fertilizers with potassium phosphate and the application of mulch combination PE - black foil and agrotextiles and amounted to 45,997 kg / ha in 2021. The lowest yield of lettuce was registered in the control variant and amounted to 22,487 kg / ha in 2020.

Objectives: 1) develop a thorough understanding of the sorption mechanisms of Pi and Po onto the Al/O- WTR; 2) determine the breakthrough range of the composite Al/O-WTR during P capturing from agro- wastewaters; and 3) critically evaluate the performance of the composite Al/O-WTR as a fertilizer using selected plants grown in lysimeters and test-field studies. Instead of lysimeters we used pots (Israel) and one- liter cone-tainers (USA). We conducted one field study but in spite of major pretreatments the soils still exhibited high enough P from previous experiments so no differences between control and P additions were noticeable. Due to time constrains the field study was discontinued. Background: Phosphorous, a non-renewable resource, has been applied extensively in fields to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Our proposal impetus is the need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings. Major Conclusions & Achievements: An innovative approach was developed for P removal from soil leachate, dairy wastewater (Israel), and swine effluents (USA) using Al-based water treatment residuals (Al- WTR) to create an organic-Al-WTR composite (Al/O-WTR), potentially capable of serving as a P fertilizer source. The Al-WTR removed 95% inorganic-P, 80% to 99.9% organic P, and over 60% dissolved organic carbon from the agro-industrial waste streams. Organic C accumulation on particles surfaces possibly enhanced weak P bonding and facilitated P desorption. Analysis by scanning electron microscope (SEM- EDS), indicated that P was sparsely sorbed on both calcic and Al (hydr)oxide surfaces. Sorption of P onto WW-Al/O-WTR was reversible due to weak Ca-P and Al-P bonds induced by the slight alkaline nature and in the presence of organic moieties. Synchrotron-based microfocused X-ray fluorescence (micro-XRF) spectrometry, bulk P K-edge X-ray absorption near edge structure spectroscopy (XANES), and P K-edge micro-XANES spectroscopy indicated that adsorption was the primary P retention mechanism in the Al- WTR materials. However, distinct apatite- or octocalciumphosphatelike P grains were also observed. Synchrotron micro-XRF mapping further suggested that exposure of the aggregate exteriors to wastewater caused P to diffuse into the porous Al-WTR aggregates. Organic P species were not explicitly identified via P K-edge XANES despite high organic matter content, suggesting that organic P may have been predominantly associated with mineral surfaces. In screen houses experiments (Israel) we showed that the highest additions of Al/O-WTR (5 and 7 g kg⁻¹) produced the highest lettuce (Lactuca sativa L. var. longifolial) yield. Lettuce yield and P concentration were similar across treatments, indicating that Al/O- WTR can provide sufficient P to perform similarly to common fertilizers. A greenhouse study (USA) was utilized to compare increasing rates of swine wastewater derived Al/O-WTR and inorganic P fertilizer (both applied at 33.6, 67.3, and 134.5 kg P₂O₅ ha⁻¹) to supply plant-available P to spring wheat (TriticumaestivumL.) in either sandy loam or sandy clay loam soil. Spring wheat straw and grain P uptake were comparable across all treatments in the sandy loam, while Al/O-WTR application to the sandy clay loam reduced straw and grain P uptake. The Al/O-WTR did not affect soil organic P concentrations, but did increase phosphatase activity in both soils; this suggests that Al/O-WTR application stimulated microorganisms and enhance the extent to which microbial communities can mineralize Al/O-WTR-bound organic P. Implications: Overall, results suggest that creating a new P fertilizer from Al-WTR and agro-industrial waste sources may be a feasible alternative to mining inorganic P fertilizer sources, while protecting the environment from unnecessary waste disposal.
