The Content of Nutritional Elements in Gray Forest Soil and Spring Wheat Yield in Relation to the Aftereffect of Lime and Mineral Fertilizers in an Alternating Crop Rotation

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 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.

The results of two–year (2018–2019) studies on the effect of various seeding rates and nutritional backgrounds on the yield and grain quality of two types of spring wheat – soft wheat and emmer wheat (spelt) – are considered. The agrochemical characteristic of the gray forest soil of the experimental plot is as follows: the humus content in the layer of 0–20 cm was 2.9–3.4 % (Tyurin method), mobile phosphorus amount was 176–241 mg, exchange potassium amount was 77–109 mg/kg of soil (Kirsanov method). The degree of saturation with bases was 85.2–87.7 %, the pH of the salt extract was 5.6–5.8. Agrometeorological conditions of 2018–2019, on the whole, met the requirements for early spring crop seeding, HTC (hydrothermal coefficient) was 0.85–1.2. Two levels of mineral nutrition were studied in the experiment (natural background, without fertilizing, NRK for the planned grain yield of 3 t/ha), four seeding rates against each nutrition background: 4, 5, 6 and 7 million germinating seeds per 1 ha. The seedling completeness in both types of wheat over an average of 2 years depended on the seeding rate, regardless of the background of nutrition. In soft wheat of Ulyanovskaya 105 variety, against a natural background, with an increase in the sowing rate from 4 to 7 million germinating seeds per ha, the seedling completeness decreased and amounted to from 82.5 to 76.3 %, in spelt, it was 84.7–78.6 %. On a fertilized ground it was, respectively, 83.4–78.0 and 84.1–77.6 %. Good preservation of plants in both types of wheat from the number of sown seeds and seedlings was noted when the sowing rate was reduced from 7 to 4 million: without fertilizer 82.6–88.5 % in common wheat and 83.5–90.4 % of spelt. On a fertilized ground it amounted, respectively, to 84.3–90.5 and 86.5–92.3 %. Changes in nutritional background by introducing calculated doses of mineral fertilizers for all options with seeding rates on average for 2018–2019 yielded an increase in soft wheat by 0.94 tons of grain per hectare and by 0.61 tons of spelt. The highest conversion efficiency of fertilizers at a sowing rate of 6 million in common wheat was 8.1 kg of grain per 1 kg of a.a., for spelt at a sowing rate of 4 million the figure was 5.6 kg per 1 kg of a.a.

Co2 Intensity

The article presents the results of research on the biological activity of gray forest soil depending on the systematic use of organic and mineral fertilizers. It is established that effective reproduction of humus in gray forest soil is provided by organo-mineral (12 t of manure together with N80P60K80 application per 1 ha of crop rotation area) and organic (24 t/ha of manure), respectively 36,5 t/ha, and 35,6 t/ha. The application of only mineral fertilizers in the norm of N80P60K80 per 1 ha of crop rotation area resulted in a decrease in humus reserves by 9 % relative to the initial level (32,4 t/ha). The highest degree of humification of organic matter provided the option of applying organic fertilizers (60 t/ha) both separately – 36,0% and compatible with mineral – (60 t/ha manure + N80P60K80) – 34 %. Prolonged use of organic and mineral fertilizers in crop rotation significantly increased the total number of microorganisms in the soil. The result was increased decomposition of organic matter and increased release of CO2 from the soil. The areas with the highest biological activity and CO2 intensity were characterized by areas where the soil was systematically enriched with fresh organic matter. The intensity of biological processes in the organo-mineral system increased by 67 % relative to the variant without fertilizers and by 30 % relative to the variant with only N80P60K80. The use of organic and mineral fertilizers in one system stimulated the process of decomposition of fiber – at the level of 78,5 %, which in percentage terms exceeded the value of the indicators obtained for a purely mineral fertilizer system.

Grey Forest Soil

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.

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.
