DEGRADATION OF AGROCHERNOZEMS AND WAYS TO ELIMINATE IT ON THE SLOPES IN THE ROSTOV REGION

In recent years, the problem of soil fertility has been relevant. We conducted research in a multifactorial long-term experiment on the study of erosion processes in 1990-2022. The experiment is located on the slope of the Bolshoy Log beam, Rostov region. It was revealed that the contour-strip organization of the slope area with a steepness of 3.5-4° and soil protection tillage made it possible to reduce runoff and soil flushing to safe limits. The use of perennial grasses in crop rotation increases the erosion resistance of the field.
