In modern conditions of agricultural intensification, the use of a scientifically based fertilizer system becomes extremely necessary. It is she who will allow you to get economically viable crop yields. Studies to obtain the planned yield with the introduction of increasing doses of mineral fertilizers were carried out in 2018-2020 in the forest-steppe zone of the Urals. The soil is old leached chernozem. Experiment scheme: control (without fertilization); application of mineral fertilizers to the planned yield: by 3.0 t/ha of grain N40 P75; 4.0 t/ha - N95P110; 5.0 t/ha - N150P200 and 6.0 t/ha - N185P160 kg of active ingredient. On average, over the years of research, the planned yield of spring wheat was achieved. The cost of growing spring wheat without mineral fertilizers amounted to 16850 rubles/ha. The introduction of mineral fertilizers for the planned harvests increases costs up to 34200 rubles/ha. Such high costs are explained by the use of phosphate fertilizers, whose price is twice as high as ammonium nitrate. In the structure of costs for obtaining a yield of 3.0 t/ha of grain, the share of mineral fertilizers accounts for 17 %. A further increase in the level of mineral nutrition through fertilizers increases the share of fertilizer costs up to 45 %. The profit from the sale of grain on the option with NPK of 6.0 t/ha of grain reached 27400 with a profitability of 80 %. On the control, the corresponding indicators were 5150 rubles/ha and 31 %. The optimal and economically justified is the level of mineral nutrition, providing 4.0 t/ha of spring wheat grain. A further increase in the agricultural background is associated with a risk due to the peculiarities of weather conditions in the forest-steppe zone of the Urals

The Impact

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

Chernozem Soils

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

Spring Soft Wheat

The results of studying the influence of elements of the technology of cultivation of spring wheat (various predecessors, methods of basic tillage, doses of mineral fertilizers) in order to obtain grain that meet the food requirements (GOST 9353-2016) are presented. The studies were carried out in 2015–2017 in the Ulyanovsk region in the forest-steppe zone on leached chernozem. The object was the Ulyanovskaya 105 spring soft wheat variety, which has been recommended for cultivation in the Volgo-Vyatka (4), Middle Volga (7), Ural (9) regions of the Russian Federation since 2017. The scheme of the experiment provided for placement after peas and winter wheat, autumn main dumping and shallow tillage. In each of the options, the sowing was carried out using three backgrounds of mineral fertilizer – N24Р6 К0 kg/ha a.i. before sowing; N64Р18К35 kg/ha d.v. before sowing + retardant “Tse Tse Tse 750” (chlormequat chloride); N50Р30К70 kg/ha d.v. before sowing + N25 in tillering + N30 after heading + retardant “Tse Tse Tse 750”, calculated for the planned yield of 4.0; 5.0 and 6.0 t/ha, respectively. The meteorological conditions in the years of research were characterized by uneven precipitation (HTC in 2015 – 0.7; in 2016 – 0.8; in 2017 – 1.4). The grain yield of the studied variety of spring soft wheat on average for the variants of the experiment ranged from 3.82 t/ha to 5.60 t/ha with its high quality. The largest amount of protein (720–760 kg/ha) and grain weight per ear (1.07–1.08 g) were formed by the predecessor of peas after plowing against the background of the introduction of mineral fertilizers in doses calculated for the planned yield of 5.0–6,0 t/ha. In terms of the content of crude gluten (28.1–30.9%), in nature (786–798) and vitreousness (87–91%), the grain corresponded to the indicators of class 2, in terms of protein content in the grain (12.5–13.5%) – indicators of the 3rd class of GOST 9353-2016. Higher quality grain with a higher yield level was formed according to the pea predecessor. The coefficient of elasticity of flour dough within the normal range for strong wheat (0.70–0.85) was observed on all variants of plowing and on 1 background of mineral fertilizers for fine processing according to the predecessor winter wheat, as well as on 1 and 2 backgrounds of mineral fertilizers according to to both methods of basic tillage according to the pea precursor. According to the general baking assessment (4.1–4.4 points), the Ulyanovskaya 105 variety corresponded to the norm for valuable crop varieties.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The article presents the results of field research conducted in 2018-2019 on leached Chernozem of the Volga forest-steppe. The objects of research are varieties of spring wheat-Tulaykovskaya 10, Yoldyz and Tulaykovskaya 108. At different seeding rates of 5.0 and 5.5 million germinating seeds per ha, the effect of mineral fertilizers on 1 ha was studied. They were represented by a complete mineral fertilizer (azofoska) and fertilizing with a mineral nitrogen fertilizer in the tillering phase at doses of 30, 60 and 90 kg of AD/ha against this background. Analysis of the yield of spring wheat varieties indicates that the harvest of grain variety Yoldyz in variants with a seeding rate of 5.5 million germinating seeds per ha against the background of the application of ammonium nitrate at a dose of 60 kg of DA (2.52 t/ha) was superior to other varieties Tulaykovskaya 10 and Tulaykovskaya 108 (2.51 and 2.46 t/ha). The maximum increase in seed productivity when adding ammonium nitrate in the tillage phase of the crop was in Tulaykovskaya 10 variety (0.34 t/ha), the lowest in the Yoldyz variety (0.06 t/ha) compared to the variant with amofoska application in the pre-sowing cultivation. When increasing the doses of nitrogen fertilizers there was an increase in the water content of all the studied varieties by 1-3 PCs. While increasing the seeding rate from 5.0 to 5.5 million germinating seeds per 1 ha the number of grains in the ear changed on average for varieties by 1-2 PCs. Of all the studied varieties, the largest mass of 1,000 grains was in the Yoldyz variety (40.56 g) after azofoska application in the presowing cultivation + N60 during tillering at a seeding rate of 5.0 million germinating seeds per 1 ha, the smallest in the Tulaykovskaya 108 variety (37.87 g) after azofoska application at a dose of 0.15 t/ha at a seeding rate of 5.0 million   germinating seeds per 1 ha.

The importance of sulfur for a balanced nutrition of grain crops is demonstrated. The content of mobile forms of sulfur in the main zonal soils of the Kursk region – black soil and gray forest soils is given. Gray wooded soils have a low content of mobile sulfur in most areas of the region. The availability of sulfur in black soil ranges from low to medium. Practical studies on the effectiveness of different types and forms of using sulfur-containing mineral fertilizers in the cultivation of spring wheat on zonal types of soils in the south-western forest steppe of the Central Black Earth Region have been performed. Research has found that the practicability of using sulfur-containing mineral fertilizers and their agronomic effectiveness is directly associated with the content of available forms of sulfur in the arable layer of the soil. It is most effective and reasonable to use sulfur-containing mineral fertilizers in the cultivation of spring wheat on gray wooded soils. The practical data obtained prove the urgency of the use of sulfur-containing fertilizers in technologies for the cultivation of grain crops on soils with inadequate content of available forms of sulfur.

In the results of research are presented the regularities of the formation of cenoses of segetal vegetation in field crops, in particular, corn for grain and soybeans, with adaptive tillage systems in the Forest-Steppe zone of Ukraine in order to develop effective, environmentally safe, resource-and energy-saving agrotechnological measures to control the level of contamination of agricultural land. The research was carried out during 2016-2020 in a stationary two – factor field experiment, which includes 5 alternative tillage systems (plowing, flat – cutting processing, differentiated – chiseling, shallow and surface – disking) and 3 fertilizer systems (without fertilizers; earning in the soil by – products of the predecessor; by-products + mineral fertilizers) in a short-term grain crop rotation (winter wheat-corn for grain-spring barley-soy) on gray large-sawn-light loamy forest soils.It was found that in agrocenoses of corn for grain and soybeans during the growing season, a small-year type of contamination is formed with a predominance of representatives of the Poaceae family, the monocotyledonous class, in particular Echinochloa crus-galli L. and Setaria glauca L.The best results in controlling of the development of segetal vegetation on experimental variants were provided by varieties of deep tillage (plow, flat-cut or chisel) against the background of an organic-mineral fertilizer system with the introduction of by-products of the predecessor into the soil and the introduction of mineral fertilizers. Such fertilizer systems decreased the contamination of crops by 38.9%.When cultivating the soil without turning the soil chunk – flat-cut and disking, against the background without fertilizers, the development of segetal vegetation was poorly controlled.Systems of minimized–shallow and surface disk treatments significantly (up to 88%) increased the abundance and (up to 91%) weight indicators of crop weed contamination in the pre-harvest period compared to multi-depth plowing and differentiated system of basic soil tilling.
