“…The 30-50 cm layer is not cultivated, but it experiences a serious mechanical load from the movers of agricultural machinery and working bodies (plow, opener) of agricultural implements. In the layer of 50-70 cm, there is a zone of accumulation of silt particles transported by water from the overlying layers [5].…”

The article presents the results of researches on the change in the physical properties of leached chernozem during the cultivation of spring wheat according to the basic tillage options (moldboard, non-moldboard, differentiated, No-till) for three crop rotations (annual grass-spring wheat-spring wheat) and fallows. In the course of the field study of the water permeability of the subsurface layers of leached chernozem, it was found that moldboard and non-moldboard basic tillage have the maximum negative impact. They reduce the infiltration rate from a depth of 30 cm to 1.7, and from a depth of 50 cm - 2.2 mm/min. Also, the abovementioned systems of basic tillage reduce filtration to minimum values of 1.0-1.2 mm/min. The minimum negative effect was noted at differentiated tillage, in which the water permeability of the subsurface layers approaches the values of long-term fallow. The rate of absorption and movement of water in unsaturated soil changes relatively quickly, affecting the reserves of productive moisture, aeration of the root zone, and through them affects the productivity of the arable land. The productivity of the crop rotation with a seed fallow (annual grass-spring wheat spring – wheat spring) is reliably higher than the control according to the differentiated treatment; and it is 40% less according to the No-till basic tillage.

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.

Restoration of post-tech ecosystems of the Western region of Ukraine takes place both through natural self-overgrowth with vegetation and through the implementation of phytomeliorative measures - artificial afforestation of disturbed areas. These processes have been studied on post-technogenic territories of Kolomyia lignite and Yaziv sulfur deposits. Transformational processes in the study area are caused mainly by three factors: natural succession of vegetation (from the emergence of mosses and pioneering species of grasses and trees to the formation of stable plant communities); human economic activity (phytomeliorative measures for sowing grasses and creating forest crops) and cattle grazing (appearance of fruit tree species in phytocenoses). Transformational processes in edaphotopes are primarily determined by two factors - the natural succession of vegetation and erosion processes. Due to the long process of restoration of disturbed ecosystems in post-man-made areas, relatively complex and rich in species composition stable plant communities are gradually formed, which contribute to the formation of embriozems, identification of soil genetic horizons, increasing the thickness of the soil profile and approximating the physical and mechanical properties of the upper layers of the soil to the properties of natural zonal soils. The species composition and structure of vegetation in the post-technogenic territories of Kolomyia lignite and Yaziv sulfur deposits of the Western region of Ukraine have been determined. The study showed that the dendroflora of post-technological areas is represented by 59 species of tree plants.Changes in the components of phytocenoses and edaphotopes are presented and the factors of transformation processes in disturbed ecosystems are analyzed. Stages of natural succession of vegetation in post-technogenic territories of lignite and sulfur deposits have been established. Physico-chemical properties of the formed embriozems were analyzed and their comparative analysis with zonal soils was carried out. It is established that the processes of vegetation restoration and soil formation in post-technogenic territories cause the gradual formation of complex plant groups and relatively stable and stable natural ecosystems.
