Abstract The article presents the results of studies on the effect of humic fertilizer Gumostim and mineral fertilizers on the formation of productivity of spring soft wheat varieties Tulaykovskaya 108. The work performed allows us to expand our understanding of the effect of humic acid salts in humic fertilizers on the development of spring wheat and give recommendations on methods for their use in order to increase the yield and quality of household products, preserving the ecological cleanliness of the environment. The research objective is to improve the elements of spring wheat cultivation technology under the conditions of the forest steppe of the Middle Volga region, which allow to optimize the conditions of growth and development through the integrated use of humic and mineral fertilizers. Studies have found that the use of humic fertilizer Gumostim increases field germination of spring wheat seeds by 0.8-1.2%, the net productivity of photosynthesis to 5.16 g/m2 × day, ear grain content by 13%, grain weight per plant by 15%, yield by 0.55 t/ha. Mineral fertilizers increase the net productivity of photosynthesis to 5.30 g/m2 × day, ear grain content by 36%, spring wheat yield by 1.01 t/ha. The combined use of Gumostim and mineral fertilizers increases the net productivity of photosynthesis to 5.47 g/m2 × day, ear grain content by 83%, grain weight per plant by 45.8%, spring wheat yield by 1.55 t/ha.

Full textAbstract:
The review analyzes the effect of organic-mineral fertilizers (OMF) on morphogenesis, physiological processes, productivity and fruit quality of edible tomato (Lycopersicon esculentum Mill.). Tomatoes are known to play a primary role in providing the population with quality vegetable products, due to a large number of sugars (2.5–4.2 %), organic acids (0.4–0.9 %), vitamins, lycopene (0.3 %), fiber (0.3–0.9 %), mineral and aromatic compounds. The annual rate of human consumption of tomatoes, according to scientists, should be 39 kg.
It is noted that the use of OMF and humic preparations is an integral part of organic farming. According to DSTU ISO 4884: 2007 organic-mineral fertilizer is a fertilizer obtained by physical and / or chemical interaction of organic and mineral components.
Growing tomatoes using organic technology reduces the size of the fruit, but makes tomatoes more tasteful compared to fruits grown in the traditional way, the accumulation in the fruit of useful iron, magnesium, vitamins and minerals. It is shown that humic compounds have a positive effect on all phases of the mitotic cycle of cells and increase the value of the mitotic index by 1.5 times, resulting in increased root formation, changes of cell membranes increase water supply and nutrients. Treatment of seeds before sowing with liquid complex nitrohumine fertilizer containing macro- and microelements increases germination by 10%. Feeding tomato plants with liquid OMF during the growing season allows to intensify the process of photosynthesis, ensure better development of the leaf surface and root system, increase the laying of more reproductive organs and reduce disease incidence, resulting in a 40 % increase in yield and improved quality. The stimulating effect of humic acids on rooting of tomato seedlings, growth processes, increase of resistance to temperature decrease is revealed.
Growth stimulants and liquid nitrogen fertilizers also streamline growth, increase productivity and quality of tomatoes.
Thus, the use of organic-mineral fertilizers based on humic substances affects the development of edible tomatoes, streamlines the physiological processes in plants, their resistance to abiotic and biotic factors, fruit yield by 26–51 % and their quality, morpho-biometric and biochemical parameters of seedlings.

There were considered the results of experiments with fertilizers, which were carried out with scientific fertilizers on the chernozem chestnut soils of the arid Volga region. The objects of research were grain fodder crops (spring barley, oats, grain sorghum, grain corn), as well as those used for green fodder (sugar sorghum, corn). It has been established that among mineral fertilizers, the leading role in yield increasing of forage crops belongs to nitrogen fertilizers but not phosphorus ones (as previously believed). The use of fertilizers based on humic acids had a positive effect on the growth, development and yield increase of forage crops. The maximum productivity in the experiments was achieved with the combined use of mineral nitrogen fertilizers and humic based products. The effect of all studied types of fertilizers depended on the weather conditions of the growing season.

Full textAbstract:
The studies on assessment of changes in the content and composition of soil organic matter under the influence of the systematic use of mineral fertilizers (NPK)1, (NPK)2, (NPK)3 against the background of the aftereffect of single liming in doses of 1.0 and 2.0 h. a. (control – variants without fertilizers and lime) were conducted in the conditions of the Nizhny Novgorod region in a long – term stationary experiment on light-grey forest soil. The research was carried out upon comple-tion of the fifth rotation of the eight-field crop rotation. The results of the study showed that for 40 years (from 1978 to 2018) the humus content in the soil (0-20 cm) decreased by 0.19-0.52 abs. % in variants as compared to the original (1.60 %); though, humus mineralization was less evident against the background of long-term use of mineral fertilizers compared to non-fertilized control. The higher humus content in the topsoil was noted in the variants with minimal (NPK)1 and increased (NPK)2 doses of fertilizer – 1.41 and 1.25 %, respectively. The humus content in non-fertilized soil and when applying high (NPK)3 doses of mineral fertilizers was almost identical – 1.08-1.09 %. The predominant group in the composition of humus were humic acids, the content of which in the experiment on average was 37.8 % of the total carbon with an evident decrease from 42.6 % in the control to 31.8% when applying increased doses of mineral fertilizers. The aftereffect of liming, carried out in 1978, was unstable and did not significantly affect the content and composition of soil organic matter.

The article describes results of the microplot field trial to investigate potential use of metallurgical slags for fracture of capillary rim during reclamation of toxic waste dumping areas, such as enrichment plants tailings, solid waste dumps, etc., with minimal possible introduction of fertile soil layer. Such approach allows energy-effective utilization of metallurgical wastes. Four slags, produced at EVRAZ West Siberian plant by different technologies were used: white nonferrous, blast-furnace, converter and electric furnace slags. These slags were used as an inert material, underlying thin fertile soil layer in experimental microplots, where perennial plants (legume-grass mixture) were sawn. For each slag there was check variant (no fertilizer added), and variants with potassium humic agents, and their combination as mineral fertilizers. Aboveground phytomass at the end of the grow ing season varied from 17 to128 g/m2. Converter and blast furnace slags, which had the least phytotoxicity, appeared to be better inert materials. Mineral fertilizer, introduced itself and combined with humic agents, has increased aboveground phytomass 2 – 4 times as compared with check variant. Used separately, humic agent did not affect plant production, whereas used together with mineral fertilizer, it increased phytomass 1.6 – 1.8 times. Thus combined introduction of mineral fertilizer and humic agents is recommended to stimulate germination abilit y and phytomass production. Converter and blast furnace slags can be used as inert materials for reclamation with minimal fertile soil layer application, whereas white non-ferrous and electric furnace slags are not recommended for such application due to their high phytotoxicity, negatively affecting growth and development of perennial plants, used for reclamation.

Established that liming with single dose by hydrolytic acidity (1,0 Hg) slows down the processes of organic matter mineralization in gray forest soil: without mineral fertilizers – in 2,1 times, with mineral fertilizers – in 4,1, with plowing of the seed crop biomass and the by-products of the predecessor – in 1,4 times. The mineralization of nitrogen compounds as a result of liming also proceeds slower: without mineral fertilizers – in 1,2 times, with mineral fertilizers – in 2,2 times. Confirmed patterns that were obtained in previous years of research about the impact of liming on the activity of humus mineralization – it decreases as a result of liming with full dose (1,0 Hg) without mineral fertilizers by 66,7 %, with mineral fertilizers – by 4,4 %. The total biological activity in the soil without a mineral fertilizer increases as a result of liming by 23,0 %, with mineral fertilizers – by 42,5, at the background of exogenous organic matter (EOM) plowing – by 83,7 %. Liming allows to reduce the level of phytotoxicity of soil without mineral fertilization by 17,9 %, %, with mineral fertilizers at the background of EOM – by 12,2 %. Positive influence of liming is amplified in variants with introduction of organic matter into the soil (byproducts of predecessor and siderate). Plowing of siderate crop biomass and by-products of predecessor in crop rotation allows to slow down the processes of organic matter accumulation in soil. The application of liming and mineral fertilizers in combination with the introduction of EOM reduces the index of pedotropy in 2,1 times, only with mineral fertilizers (N60Р30К60) – in 1,5 times. Similarly, plowing of the EOM affects the intensity of other mineralization processes. The total biological activity increases as a result of EOM plowing into the soil: in the variant with the use of mineral fertilizers by 54,7 %, with mineral fertilizers and liming – by 28,9 %. Confirmed previously established laws regarding the impact of optimization of mineral nutrition on the activity of decomposition of humic substances: with an increase in the dose of mineral fertilizers in 1,5 and 2 times the activity of mineralization of humus decreases by 6.0 and 10,1 % respectively. With the improvement of mineral nutrition of plants, the amount of root extracts is increased, which is a more accessible substrate than humus acids, which leads to slowing down of the destruction of humus substances.

Full textAbstract:
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.

When improving agricultural technologies, considerable attention should be paid to the use of organic fertilizers, which involves the use of humic and fulvic acids. This will reduce the use of mineral fertilizers and increase the yield of agricultural products, as well as grow environmentally friendly products. Justification of the use of organic fertilizers to stimulate plant growth requires a preliminary study of their action under laboratory conditions. The article analyzes the wide application of biotesting procedures based on the reactions of living organisms, using plant test-objects. The availability of a wide range of plants allows their use for testing various factors, including the analysis of the stimulating effect of substances on higher plants. The purpose of the study was to study the effect of the organic fertilizer «Grееnat» on the initial growth processes of higher plants in the laboratory by biotesting. The methodology of the study was to apply the biotesting method using higher plants widely used in agriculture, namely barley (Hordeum vulgare L.), soybeans (Glycine max L.), wheat (Triticum aestivum L.), maize (Zea mays L.), cucumber (Cucumis sativus L.), tomato (Solanum lycopersicum L.). Іt is established that the declared organic fertilizer «Greenat» contains: humic acids (67,68 g/dm3), fulvic acids (24,37 g/dm3) and organic substances (53,39%). The stimulating effect of the studied fertilizer on the initial processes of growth and formation of the root system of representatives of the group of cereals – barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) was revealed. Stimulating effect of organic fertilizer is also established for the initial growth processes of soybeans by estimating the length of shoots (increase by 38%) and for the initial growth processes of corn by estimating root length (increase by 22%). Root length of cucumber and tomato increased by 23 and 21% respectively, indicating the stimulating effect of the organic fertilizer «Greenаt» in the treatment of seeds of vegetable crops. The results of the research indicate the effectiveness of using the organic fertilizer «Grееnat» at the stage of seed treatment to stimulate the energy of germination and development of the root system of plants.
