Today, in the scientific and practical field, as well as a long time later, much attention is paid to improving the quality and quantity of yield. To obtain the desired results, we considered various systems of basic soil tillage in the growing of winter wheat, namely, determined the influence of basic soil tillage systems on the autumn development of winter wheat in the Luhansk region. The results of research of the influence of the basic soil tillage and the forecrop on the density and content of productive moisture in the soil layer of ordinary chernozems and on the autumn phases of development of winter wheat variety "Antara" are discussed. The research was performed in 2018-2020 in the fields of the department of scientific and technical training in agronomy and farms located in the north-central moderately arid subzone of Luhansk region. Three methods of soil tillage have been studied by us: moldboard ploughing -depth 22 cm; moldboard-less disking ploughing -depth 10 cm; moldboard-free subsurface cultivation -depth 12 cm. Forecrops: occupied fallow, sunflower, maize. The research was performed according to generally accepted methods. By means of research was established the advantage of moldboard ploughing over moldboardless ploughing. Moldboard soil ploughing contributed to the creation of lower density in the arable horizon under different forecrops, greater microbiological activity of the soil, better water supply during the autumn vegetative season. Moldboard ploughing increased access to nutrients such as potassium and nitrogen, and moldboardless ploughing accumulated available phosphorus. Improving the agrophysical properties of the soil contributed to the formation of better biometric indices in the autumn vegetative season. The height of the plants where the soil was plowed to the depth 22 cm was higher compared to the height of the plants with moldboard-less disking ploughing to the depth 10 cm. This affected the number of stems, which also increased, the number of leaves and roots increased, respectively. The depth of the tillering node increased relative to the increase in the depth of soil tillage, the weight of 100 absolutely dry plants increased, respectively, almost three to four times. Thus, the basic soil tillage improves the agrophysical properties, increases the microbiological activity of the soil and improves the biometric indices of plants.

The results of the studies of changes in biological and enzymatic activity of soils depending on the anthropogenic influence and the size of soil aggregates are presented. The work was carried out in 2015-2021 in the conditions of the south-east of the Central Chernozem region. The soil of the experimental site is ordinary (segregational) medium–sized medium-humus heavy loamy chernozem. The objects of research are long–used arable land and the layland used for haying since 1882. The quantitative change of individual groups of microorganisms, determined by the nature of the impact on the soil cover, is shown. The total number of microorganisms in both arable land and chernozems under natural vegetation was at the same level of 40.0 and 39.3 million CFU, respectively. Significant differences in the biological activity of chernozems by individual groups of microbial cenosis structure were noted. An increase in the number of ammonification bacteria on the arable analogue was revealed by an average of 30.7%; micromycetes by 4.4%; cellulolytics by 46.4%; nitrifiers by 46.9%; calculated humification coefficient by 45.4%. According to other components of microbial cenosis, the advantage of layland steppe soils is noted: actinomycetes by 18.5%; humus mineralizers by 11.8%. An increase in the activity of most groups of microorganisms was shown in the smaller structural units of 1-5 mm. In larger mesoaggregates, CFU numbers tend to decrease. This pattern is most clearly traced in agrogenically altered soils. In the soils occupied by natural vegetation, there is a higher activity of biochemical processes.
