Description
Summary:When creating environmentally sustainable agricultural landscapes, an important role is given to the rational use of the lands of the hydrographic fund, especially ravine-gully. These lands experience the greatest erosion load, since water flows from them from the entire catchment area through them. They are more affected by ravines and need reclamation not only from the standpoint of increasing land productivity, but also from the standpoint of protecting rivers and reservoirs from the products of flushing transported through these systems. In addition, the prevention of new ravine formation, the suspension of growth or the reclamation of ravines on these lands will save from the destruction of arable land on the slopes adjacent to the beam network. According to the agro-ecological state of the lands of the hydrographic fund, it is possible to judge the anti-erosion structure of the arable land and, in general, the agrolandscape. In the Central Black Earth Zone, due to the considerable plowing of the territory, the lands of the hydrographic fund are mainly occupied by natural fodder land, the yield of which does not exceed 40 kg / ha of green mass. More than half of the area of these lands is eroded, and about 120 thousand hectares are affected by ravines and practically excluded from agricultural use.
