The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.

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 deals with the influence of mineral fertilizers and the long-term aftereffect of liming on the biological properties of light gray forest soil and the yield of meadow clover 1 g.p. in the conditions of the South-East of the Volga-Vyatka region. The biological properties of light gray forest soil in 2020 were more influenced by the weather conditions of the pink clover vegetation and the culture itself than by the studied aftereffects of lime material and various doses of its mineral nutrition. The biological activity of the soil was in the range of 16.3–30.4%. The intensity of soil respiration was very weak and was in the range of 1.53–3.4 mg of CO2/10g for 24 hours. The average yield of the green mass of clover 1 g.p. (in terms of absolutely dry matter) was in the range of 30.4–33.2 t/ha (NSR05 by factor B-6.3) and did not depend on the aftereffect of the studied lime doses. The use of N45P120K180 doses of mineral fertilizers increases the average yield of pink clover 1 g.p. compared with the natural fertility of light gray forest soil and the variants of using N15P40K60 doses up to 37.9 t/ ha, which is by11.9 and 8.6 t/ha respectively higher than these variants (NSR05 for factor A-5.2). An increase was also obtained from the use of N30P80K120 doses of mineral fertilizers compared to the cultivation of clover according to natural soil fertility — by7.4 t/ha (NSR05 according to factor A-5.2).I n general, for 42 years of studying the aftereffect of liming it was shown, that by 2020 liming does not affect the biological properties of light gray forest soil and the yield of 1 g.p. clove according to all the studied doses of its use in the conditions of the South-East of the Volga-Vyatka region. The soil needs repeating of reclamation works.

Agrochemical Properties

We studied the changes in the agrochemical properties of the gray forest soil in the territory of Western Siberia’s sub-boreal zone affected by the long-term use of the organomineral fertilizers in the grain-follow-row crop rotation and in its absence. We used virgin areas of gray forest soil situated in the immediate proximity to the fields as a control. The anthropogenic changes of morphological features throughout the gray forest soil profile were identified based on the use of fixed permanent plots laid down in 1960. This paper describes the dynamics of the actual, exchange, and hydrolytic acidity as well as the amount of absorbed bases, together with the base exchange capacity and the degree of base saturation. The study of arable gray forest soil for the period 1960-2020 was performed. This provided an opportunity to identify the causes of its chemical degradation in the sub-boreal zone of the Trans-Urals under the conditions of a plant residue shortage. The systematic use of mineral fertilizers affects the base exchange capacity and triggers an increase in the arable layer’s acidity. The use of an organic fertilizer system stabilizes the chemical properties of gray forest soil.

The influence of agrotechnical measures: mineral fertilization, liming, dipping of biomass ofgreen manure culture and by-products of the precursor in crop rotation on the number andphysiological-biochemical activity of microorganisms of the root zone of spring wheat was studied.It has been established that the introduction of mineral fertilizers and liming increases the numberof microorganisms of the main ecological and trophic, functional and systematic groups andimproves physiological-biochemical activity of representatives of certain groups ofmicroorganisms. The introduction of exogenous organic matter (green manure + by-products of theprecursor) allows to reduce the number of melanin-synthesizing micromycetes in gray forest soil by7.65 %, their specific content in the total number of micromycetes by 47.4 %, reduce the level ofphytotoxicity of the soil by 43.4 %. Taking into account long-term data on increasing the numberand specific content of melanin-synthesizing micromycetes in soils of contaminated ecotops, thisgroup of microorganisms can be considered as diagnostic in assessing the general level ofanthropogenic pollution of agrophytocenoses.

Positive Effect

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

Abstract. The goal is to study the influence of the predecessor and fertilizers on the yield and quality of winter wheat grain. Methods. The studies were carried out in a long-term stationary field experiment on a gray forest medium loamy soil. Field experience, observations, accounting and generalization of research results were carried out in accordance with the methodological recommendations of B.A. Dospekhov. Statistical processing of the research results was performed using Microsoft Excel 2007 with a 95 % significance level of the results. Results. As a result of the studies, it was noted that the studied predecessors had an insignificant effect on the development of winter wheat plants in the initial phases of growth. The density of winter wheat plants during the germination period varied within the range of 314–323 psc/m2 without the use of fertilizers and 317–328 psc/m2 against the background of their application. Further growth and development of plants took place in close relationship with the studied factors. At the end of the growing season, the number of productive stems was higher on the plots, where the clover of the first year of use was used as a predecessor, both in the control (without fertilizers) and when applying mineral fertilizers. Accordingly, the yield of winter wheat grain was higher for this predecessor, averaging 35.7 c/ha for 2014–2019. Without fertilization, depending on the predecessor, 25.2–32.8 c/ha were obtained, against the background of fertilization – 34.2–39.6 c/ha of winter wheat grain. On average, over the years of research, winter wheat grain contained 10.7–14.0 % protein. Depending on the year, this indicator varied from 8.8 % to 16.8 %. At the same time, the lowest values for the protein content were obtained for the variants without the use of fertilizers. In general, the content of protein and gluten in winter wheat grain largely depended on the application of mineral fertilizers and to a small extent on the predecessor. The weight of 1000 grains, depending on these factors, changed insignificantly.

Moisture Regime

The content of mineral nitrogen was studied when it was applied at a dose of 60 kg / ha on gray forest soil of heavy particle- size distribution at various levels of phosphorus-potassium nutrition in field experiments with barley. Fertilizer doses were determined by the normative method according to the CINAS method for a planned yield of 3 t / ha. It was shown that the dynamics of nitrate and ammonium nitrogen depended on the moisture regime during the vegetation period. With excessive moisture, nitrate nitrogen, with its initial content of 4-5 mg / kg, is not detected in the arable layer by the middle of the growing season, and with a moisture deficit, less dynamism is noted. It is found in an amount of 5-7 mg / kg by the end of vegetation. The N – NH4 + dynamics turned out to be less pronounced. With an excess of moisture, its content increased to 15.6 mg / kg, and with a deficit, it decreased more than by four times from the maximum during the vegetation. In general, the content of mineral nitrogen in gray forest soil is highly dynamic, which depends on the moisture regime and the nature of its consumption by barley.
