The results of scientific research on the current state of agro-landscapes of the Southern Steppe and the main agro-technological measures to reduce the manifestation of the mentioned negative phenomena are presented. The latter is achieved by creating high-yielding mono-species agrophytocenoses of perennial legumes and leguminous grass mixtures resistant to regional climate changes, which have been observed in recent years in the southern region. Systematic expansion of lands under cereals and industrial crops which are in demand on the international market, has led to the unstable state of agricultural lands in the steppe zone of Ukraine, their area at the beginning of the XXI century being one of the highest in the world and amounting to 90.2% in Kherson region. It was found that the plough land on the territory significantly exceeds the ecologically permissible limits, as a result of which the physical and chemical degradation of soils began to increase intensively, which leads to a significant reduction in the formation of high crop yields. The consequences of these changes were highly unfavorable for the development of agriculture in all regions of the Southern Steppe of Ukraine, which is due both to plowing up extensively the agricultural landscapes and changes in the sown area structure. The main way to reduce physical and chemical degradation of areas under crops under the natural moistening conditions is the creation of high-yielding mono-species agrophytocenoses of perennial legumes and poly-species leguminous - grass mixtures resistant to extreme weather conditions of southern steppes.
