“…In accordance with the data of the agrochemical survey (2019), the arable soils of the Kursk region have a different content of macro-, meso-and micronutrients. For black soils (about 74% of the arable land area) are characterized by a higher content of macronutrients and most micronutrients [1]. They are marked by a lower content of organic matter and increased soil acidity, Table 1.…”

“…It is known that the effectiveness of the cultivation of agricultural crops is greatly influenced by climatic conditions [1][2][3][4][5][6][7][8][9]. The amount and uniformity of precipitation, the best air temperature during the growing season have a considerable impact on the development of plants, the use of nutrients from the soil and applied fertilizers.…”

“…Since most of the plant nutrients are absorbed and digested from the soil, the condition for obtaining high crop productivity is the accessibility of affordable forms of macro-(nitrogen, phosphorus, potassium), meso-(sulfur, calcium, magnesium) and micronutrients (boron, molybdenum, copper, zinc, etc.) in the soil [1]. Meanwhile, in recent years, more and more attention has been paid to meso-and micronutrients [2].…”

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 system of ecological farming, new methods and techniques for enriching the soil with organic matter, including straw, as by-products of grain crops, which account for more than 50% of the sown area, are widely used. A some-year-long experience studied the use of straw both in Russian and foreign practice, shows that physiologically active substances in the presence of nitrogen in the soil quickly decompose in the soil and straw fertilizer does not increase clogging. Moreover, the decomposition of straw depends on many reasons: temperature, humidity, fertilizer, soil biota, its abundance, specialization and compaction. With an increase in the share of mineral fertilizers, the enzyme complex of the soil is activated. When using anhydrous ammonia, the number of bacteria involved in the transformation of nitrogenous substances of the soil increases. In any form, nitrogen fertilizers enhance the development of nitrifying microorganisms, weaken negatively affecting ammonifiers. Thus, in its effect on the humus content in the soil, straw can compete with manure. The use of straw as an organic fertilizer is an important reserve for increasing productivity and stabilizing soil fertility, which should be more actively used in ecological farming.

The paper presents the results of research on the efficiency of technologies for cultivating spring wheat at various levels of intensity (extensive, intensive, resource-saving) under the conditions of chernozem soils of Kursk Region. It was found that higher reserves of available moisture and nitrate nitrogen in the arable layer of the soil before sowing spring wheat were provided by technologies with moldboard plowing. Replacing plowing with subsurface methods of tillage led to a decrease in the available moisture and nitrate nitrogen reserves in the soil for all fertilizer systems. The lowest weediness of spring wheat was observed when it was cultivated using technologies with moldboard plowing 52.3-58.3 PCs/m2, depending on the fertilizer system. The replacement of plowing with subsurface and surface tillage increased the weediness of crops to 61.7 and 73.7 PCs / m2, respectively. Application of mineral fertilizers had almost no significant effect on the number of weeds in spring wheat. The highest yield of spring wheat in all the years of studies (4,27 t/ha) was obtained in the intensive cultivation technology involving plowing at 20-22 cm, fertilization at a rate of N60Р60К60, treatment of crops with pesticides based on economic threshold of harmfulness. Yield of spring wheat, cultivated by resource-saving technologies with organic-mineral system of fertilization 0.86-4.25 t/ha depending on the methods of primary tillage. Moldboard plowing of the soil against the background of the organic-mineral fertilizer system increased the yield of spring wheat by 0.18 t/ha in comparison with subsurface tillage and by 0.39 t/ha in comparison with surface tillage. However, due to higher production costs, the best economic indicators were obtained when spring wheat was cultivated using resourcesaving technologies with an organic-mineral fertilizer system and non-moldboard methods of primary tillage.
