Abstract
Land degradation and desertification are the greatest scourges threatening human society. Global climate change and gaps in the culture of agriculture significantly increase the negative impact of these processes. The article presents the direction of degradation processes in the eroded forest brown soils of the Lori region, the qualitative characteristics of these soils, the thickness, the degree of humus content and the availability of nutrients. To mitigate erosion processes, degradation and desertification of soils, on the basis of the conducted research, it is proposed to introduce new technologies and methods of resource-saving tillage and plant care into the agricultural system. In particular, it is necessary to cultivate the soil along the contours of the slope, apply effective crop rotation schemes and fertilize the soil with high rates of organic fertilizers (25-30 t/ha). On heavily eroded and uncultivated arable lands, it is necessary to cultivate a grass mixture of legumes and cereal grasses, which will significantly reduce erosion processes.
Key words: degradation, erosion, mechanical composition, water-stable aggregates, humus, resourcesaving cultivation.
