MANAGEMENT OF SOIL EROSION IN CONDITIONS OF DIFFERENT CROP ROTATIONS AND SHELTERBELTS FUNCTIONS.

The results of modeling of potential soil losses due to surface soil runoff according to the current DSTU 7904: 2015 are considered. "Soil quality. Determination of potential threat of erosion under the influence of rains" on the slope of the field with contour-ameliorative organization of the territory (CAOT) on the lands of SE" DG Donetske" of NSC "Institute of Soil Science and Agrochemistry named after O.N. Sokolovsky" Bahmutsky district of Donetsk region, Ukraine. The main tasks of the work were: determination of potential soil losses on the slope of the fields to choose the more appropriate way of management in terms of using the working areas in the research system for black fallow, field crop rotation (excluding the impact of forest shelterbelts and taking into account the impact of shelterbelts), soil protective crop rotation. The use of working areas A and B under black fallow expectedly led to the excess of permissible soil losses in both areas, modeled according to the current DSTU 7904:2015 in Ukraine. Exceeding the allowable soil losses from erosion also occurred in section A under the conditions of its use for field crop rotation. Under the conditions of use of areas for soil protection crop rotation and in the conditions of functional compliance of forest shelterbelts, soil losses in both plots remain within the norm. In order to prevent the concentration of surface runoff from both working areas (A and B) in the lower part of the landfill, it is recommended to periodically apply the "rehabilitation" period with the organizing of soil protection crop rotation after black fallow.
