As the main means of crop production, the soil cover is an important element in monitoring studies. In the period from 1973to 2018, studies on monitoring the properties of ordinary chernozem soils of Rostov Oblast, the distribution area of which is theAzov inclined plain, were carried out on stationary sites. This made it possible to objectively assess the dynamics of soilproperties of various degrees of erosion depending on the intensity of erosion and deflation as well as human economic activity.For this purpose, an ecological profile of soil sections was laid from the watershed plateau to the foot of the slope. After analyzingthe humus profile, chemical, physicochemical, physical properties of the watershed soils and slopes, the authors have come tothe conclusion that their changes are caused by the intensification of human economic activity and an insufficient amount offertilizer applied, which is the root cause of dehumification. This led to a number of other negative changes: a decrease in thesupply of batteries, the number of absorbed bases, etc. On sloping lands, the process of dehumification is aggravated by themanifestation of erosion and the associated loss of the uppermost fertile soil layer and anti-erosion stability.
