Extensive farming in the basin of the Nura river led towidespread degradation of soils of agricultural lands and a significant decrease in their potential fertility. One of the main ones is the activation of soil erosion in anthropogenically transformed geosystems by flushing and deflation processes or complete erosion of soils by linear erosion. A significant part of agricultural land inthe Nura River basin is represented by soils that are estimated as erosion-deflation. In this connection, the authors analyze the current component indicators of the geoecological situation in the Nura basin, which allows us to systematize the criteria for its assessment in dependence on the severity of environmental degradation. Based on the analysis of the quality of surface water and the theoretical regularities of the region, the authors identify geoecological areas for the given territory.
