The variability of chemical composition of winter rye harvest under the influence of the Extrasol biological preparation, mineral fertilizers and seed dressing is considered. The values of economic and normative removal of basic nutrients in conditions of gray forest soil are established. The size of the normative removal of nitrogen, phosphorus and potassium by winter rye has been relatively stable, although slightly increased from the introduction of mineral fertilizers.

В данной статье рассматриваются вопросы влияния биологических и минеральных удобрений на продуктивность озимой ржи на темно-серой лесной почве в условиях Рязанской области. Исследования проводились по методу расщепленных делянок: на делянках первого порядка на озимой ржи изучали эффективность минеральных и органических удобрений, а на делянках второго порядка – действие биопрепаратов. Результаты исследований показали, что наилучшим из исследованных агроэкологических приемов повышения урожайности озимой ржи является использование в качестве органического удобрения соломы люпина и инокуляции семян биопрепаратами ризоагрин или флавобактерин. Урожайность зерна озимой ржи составляет от 37,5 ц/га при использовании ризоагрина и до 38,7 ц/га – флавобактерина, в среднем за 3 года. Относительно фона прибавка составляет 6,7 и 7,9 ц/га или 21,9 и 25,5%. При данном агротехнологическом приеме прибавка получена как за счет увеличения продуктивных стеблей с 495 ш/м2 до 521 шт/м2 при обработке ризоагрином и 538 шт/м2 при обработке флавобактерином, так и за счет увеличения массы зерна в колосе (35,1 г на контроле, 37,5 г при обработке ризоагрином и 37,7 г флавобактерином). Необходимо отметить, что этот максимальный уровень урожайности в опыте был достигнут без внесения минеральных азотных удобрений. В целом наблюдается прямая корреляция между содержанием азота и урожайностью озимой ржи. Вынос основных элементов питания возрастает с увеличением урожайности. This article discusses the impact of biological and mineral fertilizers on the productivity of winter rye on dark gray forest soil in the Ryazan region. Studies were carried out by the method of split plots: on plots of the first order on winter rye studied the effectiveness of mineral and organic fertilizers, and on plots of the second order-the effect of biological products. The results of the research showed that the best of the studied agroecological methods of increasing the yield of winter rye is the use of Lupin straw as an organic fertilizer and inoculation of seeds with biologics rizoagrin or flavobacterin. The yield of winter rye grain is from 37.5 C / ha using rhizoagrin and up to 38.7 C / ha from flavobacterin, on average for 3 years. Relative to the background, the increase is 6.7 and 7.9 C / ha or 21.9 and 25.5%. With this agrotechnological method, the increase was obtained both by increasing the productive stems from 495 W / m2 to 521 PCs/m2 when treated with rizoagrin and 538 PCs/m2 when treated with flavobacterin, and by increasing the weight of grain in the ear (35.1 g on the control, 37.5 g when treated with rizoagrin and 37.7 g flavobacterin). It should be noted that this maximum level of yield in the experiment was achieved without the introduction of mineral nitrogen fertilizers. In General, there is a direct correlation between nitrogen content and winter rye yield. The removal of essential nutrients increases with increasing yields.

The article presents the results of research conducted during 2016-2019 on the impact of different rates of mineral fertilizers and by-products of the predecessor on the content of chemical nutrients in plants and the yield of maize hybrids in the Forest-Steppe. The aim of the research was to establish the peculiarities of nitrogen, phosphorus and potassium accumulation in maize plants in ontogenesis in relation to the yield of hybrids of early and middle-early maturity groups to optimize the mineral nutrition of the crop. The research was conducted on dark gray wooded soil using field, chemical, calculation-weight and mathematical-statistical methods. According to the stages of growth and development of BBCH, the peculiarities of the dynamics of nitrogen, phosphorus and potassium content in plants of hybrids with FAO 190 and 280 depending on the agrochemical load of growing technology are established. Varietal regularities of concentration of chemical elements in maize plants in connection with the accumulation of dry matter by crops in ontogenesis and yield were revealed. Hybrids with the corresponding genetically determined level of nitrogen, phosphorus and potassium content in plants have been identified and its influence on the realization of genotype productivity potential has been shown. The decisive role of potassium and nitrogen in the formation of the corn crop on dark gray wooded soil has been experimentally proved and confirmed on the basis of statistical and correlation analyzes. All hybrids were characterized by high tightness of correlations between yield and content in plants of nitrogen (r = 0.760–0.934) and potassium (r = 0.755–0.943) during the growing season as opposed to phosphorus, where these connections were of medium strength (r = 0.334–0.589) and only partially close (r = 0.702–0.806). According to the results of plant diagnostics of mineral nutrition of plants, the most effective growing technologies with different agrochemical loading are singled out, which ensure the yield of early and middle-early maize hybrids in agro-climatic conditions of the Forest-Steppe at 9.56–10.39 and 11.21–12.10 t/ha.

The purpose of the research is increasing the yield of spring rape in the Tatarstan pre-Kama zone. Soil pollution affects food safety both by reducing plant performance and yield class. Oil and petrochemicals are common con-tamination sources of environment. The work is devoted to the assessment of the impact of oil pollution of the soil on the yield of spring rapeseed. The study was conducted on the experimental field of the Department of «Agro-chemistry and Soil Science» of the Kazan State Agrarian University, located in the pre-Kama zone of Tatarstan. The experimental site is presented by gray forest medium loamy soil, which is the predominant difference for this zone. The area unpolluted soil was characterized by a low content of humus and a weak acidic medium, high con-centration of phosphorus and potassium active forms. The soil was purposely contaminated with commercial crude oil by spreading over the surface at the rate of 10, 20 and 40 l/m2. These levels of soil pollution, as shown by previ-ous studies, were estimated, respectively, as low, medium and high. A close positive correlation was established between the yield of spring rapeseed and the limitation of soil contamination (R2=0.763÷0.940). Mechanical soil treatment, liming, application of mineral fertilizers and Baikal EM-1 biologics was tested for recultivation. The yield of oilseeds of spring rapeseed was closely correlated with the level of single contamination of gray forest soil with commercial crude oil for at least 15 years. Obtaining the maximum yield of spring rapeseed on oil-polluted gray forest soil was provided by comprehensive application of soil loosening, liming and application of full mineral ferti-lizer.

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.

Studies, were conducted in a stationary experiment between 1988 and 2018 on dark gray forest heavy loam soil in Scientific Research Institute of Agriculture for Northern Trans-Ural Region - Branch of Federal State Institutions Federal Research Centre Tyumen Scientific Centre of Siberian Branch of the Russian Academy of Sciences. The aim of the study is to determine the effect of long-term (30 years) impact of different systems of basic cultivation of dark gray forest soils in the cultivation of grain crops on the humus content. Observations were made according to generally accepted methods during 6 rotations of grain and fallow crop rotation: bare fallow, winter rye, spring wheat, spring vetch, spring barley, unfolded in time and space. The impact of the combined system of tillage with alternation of plowing and no-tillage at 20-22 cm during 6 rotations of a 5-pole grain and steam crop rotation (30 years), increased the humus content in the 0-40 cm layer of dark gray forest soil compared with the initial content by 0.42%. The systems of main tillage - differentiated, without sowing, and mouldboard provided in general a relatively favorable dynamics of the humus state of the soil. The content of humus in the 0-40 cm layer of soil by differentiated and unswept systems during the study period remained close to the initial condition. По отвальной системе содержание гумуса снижалось на 0,22% или в среднем 0,37т/га в год. The greatest loss of humus in the 0-40 cm layer of soil by 0.80% in relation to the initial was the impact of surface treatment with annual discing BDT-2,5 (heavy disc harrows) on 10-12 cm or an average annual loss of 1.33 t / ha.

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 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.

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.
