The features of the formation of productivity of potatoes of the Red Scarlett variety were studied during cultivation against the background of applying different combinations of organic, mineral, sideral fertilizers and straw in the conditions of the forest-steppe of the Middle Volga. The studies were carried out in the field experiment in 2014–2016 on gray forest soil with medium loam particle size distribution, on the experimental field of the Department of Plant Growing and Horticulture at KSAU. The humus content in the soil of the experimental plot was 3.48-3.65 % (according to Tyurin), labile phosphorus amounted to 128-135, exchange potassium amounted to 152–165 mg/kg of soil (according to Kirsanov), pH of the salt extract was 5.5-5.6. The experiments were performed on eight grounds with mineral nutrition. The potato yield in the reference ground due to natural fertility was 18.26 t/ha. Separate application of mineral fertilizers in a dose of N60P60K90 over an average of three years increased the tuber yield as compared to the reference of 10.19 ha, while the introduction of 60 t/ha of manure increased the yield by 8.95 t/ha. Using a traditional fertilizer system (N60P60K90 + 60 t of manure), the yield was 34.95 t/ha. As a result of the transition to the biological fertilizer system (background + green manure + straw), the yield increased to 36.26 t/ha, which is 1.31 t/ha higher compared to the traditional fertilizer system. On average, over 3 years, the maximum tuber yield of 37.48 t/ha was obtained by applying mineral and organic fertilizers, as well as straw. Sidereal fertilizers and straw provided an increase in the yield of tubers of 7.81 t/ha. The best results for the dry matter content (22.05 %) and starch (16.04 %) were demonstrated by tubers from the reference variant. More protein (2.95 %) and vitamin C (21.24 mg %) contained in tubers from the variant when mineral fertilizers were applied in a dose (N60P60K90-background) + green manure + straw.

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.

Aim. To develop the general normalized statistical model of organizing the structural state of the investigated soils, to determine the vector of direction and criteria of appraising structurization of soil variants in the Forest-Steppe on macro- and microaggregate levels of organization to obtain objective and integral information about the quality status of soil structure and to determine the critical level of degradation, when the residual resistance against the latter is lost. Methods. Field (investigated agrophysical properties of the most common variants in the Forest-Steppe of Ukraine: gray forest soil, meadow-chernozem soil, typical chernozem), laboratory (air-dried sieving of soil), statistical-analytical (fractal, factor, cluster, non-parametric statistics). Results. The combined study of the change in the state of soil structure in the most common soils in the Forest-Steppe on two hierarchy levels demonstrated the presence of soil-genetic interval in valuable structural units. The appraisal of several distribution series of structural soil units by dimensions in terms of stability using fractal indices and the structurization of agronomically non-valuable fraction of microaggregates of 0.7 and demonstrated the persistence and anti-persistence of the distribution series, namely, stability or trend. The re-grouping of soil structure constituents occurs by dimensions depending on the soil type, and microaggregates in the amount of 0.25 mm are mostly involved in structural aggregates of 1-0.25 mm and less so in more valuable structural units of >1 mm. Conclusions. It was determined that meadow-chernozem soil was the most resistant to anthropogenic impact (introduc- tion of mineral fertilizers and treatment methods). Its coeffi cient of macroaggregation was at a high level and in case of sowing perennial grasses with the introduction of fertilizers - at a very high level. Gray forest soil was found to be less resistant to the introduction of mineral fertilizers and typical chernozem was the most susceptible to agrophysical degra- dation: the macroaggregation coeffi cient was at a very low level. The microaggregation coeffi cient increased from typical chernozem to gray forest soil and meadow-chernozem which demonstrated the increase in humus content and biogenicity in the presented series of soil variants

The purpose of the work is to study the effect and aftereffect of various types and rates of fertilizers on the change in the main fertility indicators of gray forest soil, as well as the productivity of the crop rotation link. The experiments were carried out in the grain-row unit (spring wheat - corn - spring wheat - peas) of a nine-field grain-herb-row crop rotation. The scheme of the experiment provided for the study of the following options: the calculated doses of mineral fertilizers for the formation of 4 t/ha of spring wheat grain, 40 t/ha of green mass of corn, 3 t/ha of pea grain, thermally treated granulated chicken manure in doses 1, 2, 3 t/ha, bedding manure in a dose equivalent to 3 t/ha of granulated droppings, buckwheat stubble green manure sown after harvesting winter rye. Under the influence of 1-2-3 t/ha of granulated chicken manure, the content of nitrogen (Nг) in the soil increased, compared with the control, by 73.1-81.1-112.0%, respectively, phosphorus (P2O5) - by 69.3- 79.8-91.3%, potassium (K2O) - by 90.3-140-188%; in the first year of aftereffect, Nг increased by 42.6-50.5-58.4%, P2O5- by 28.6-39.3-52.1%, K2O - by 56.1-84.8-170, 7%; in the second year of aftereffect Nг - by 13.1-21.3-44.0%, P2O5- by 40.1-51.2-74.4%, K2O - by 63.3-124.1-133.1 %. When manure was applied (42 t/ha), the amount of Nг, P2O5, K2O decreased, compared to 3 t/ha of granulated chicken manure, in the year of action, respectively, by 43.4, 19.0 and 42.2%, in the first year of aftereffect - by 16.6, 22.1, 48.1%. In the second year of the aftereffect, the values of these indicators when using manure and 3 t/ha of granulated chicken manure were equivalent. In the variant with the incorporation of buckwheat green manure, the content of mobile forms of macronutrients varied similarly to manure. Under the influence of 1, 2 and 3 t/ha of granulated chicken manure, the productivity of the crop rotation link increased, compared with the control, by 78.5, 104.3, 122.6%, respectively. The effect from the action and three years of aftereffect of 42 t/ha of manure was below the level of 3 t/ha of of granulated chicken manure by 12% (productivity growth 110.6%), buckwheat green manure - at the level of 1 t/ha of granulated chicken manure (productivity growth 80.6%) ... Depending on the type and norms of fertilizers, the profitability of production was 54 ... 196%

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 aim of the research is to establish the peculiarities of the formation of the nutrient regime of gray forest soil with different systems of basic cultivation, fertilization and sealing of by-products of crops in short-rotation 4-field grain crop rotation – winter wheat–corn for grain–barley–soybean. Evaluate the quantitative inflow of biomass, participation in the formation of the nutrient regime of gray forest soil, especially the differentiation of 0–40 cm of soil layer depending on the distribution of nutrients in different tillage soil systems. The studies were carried out in a long-term stationary experiment of the department of soil cultivation and weed control of the NSC «Institute of Agriculture of the NAAS», founded in 1969. The fertilization system consisted of the application of mineral fertilizers N65Р58К68 kg acting things per 1 ha of crop rotation area. As an organic fertilizer, we used by-products of crop rotation, where during 2009–2013 received an average of 5,17–5,50 t/ha, and 2014–2017 – 6,65–7,76 t/ha of crop rotation. The existing yield of the main product significantly influenced the volume of the non-commodity part, with the growth of the main product, the growth of by-products also took place in direct proportion. Nitrogen removal averaged 105 kg/ha, and with biomass it returned on average 55,4 kg/ ha, nitrogen with a full mineralization cycle, in general, this corresponds to 45–47 % of the share of costs. In general, the return of phosphorus from by-products for the rotation of 5 received an average of 12,0–16,7 kg/ha and 4-field crop 26 rotation 19,5–22,0 kg/ha, which was 35–40 % of the total removal harvest. The soil received many times more potassium from the biomass of agricultural crops than part of the cost of the main product, due to the attraction of the maize leaf mass, from which an average of 177–253 kg/ha enters the soil, and for crop rotation – 61,4–95,4 kg/ha per hectare of sown area. Key words: gray forest soil, soil nutrient regime, recycling of nutrients, main and by-products of crops.
