Abstract
The goal of the adaptive-landscape organization of the territory is to ensure effective protection of soils from degradation under the anthropogenic impact. The experiment was performed in the permanent study area located on the slope of the Bolshoi Log clough, Aksay District of Rostov Oblast from 2016 to 2019. The use of adaptive-landscape territory organization of the slope prone to erosion allowed reducing soil erosion by 35-43%. The use of soil protection treatments as the main tillage reduced soil erosion by more than 13-24%. For this, it is provided on arable lands prone to erosion and poorly eroded areas with a degree of the slope from 2 to 3°, an extended complex of agrotechnical measures is applied. Crop rotation with 40% of perennial grasses, 20% of row crops, and 40% of winter and spring grain crops is recommended. Productivity is up to 3.9 t/ha of grain units when applying manure in a dose of 5 tons and mineral fertilizers, N46P24K30, ensuring the preservation of soil fertility at the initial level. With a 1.5-fold increase in organic fertilizers (manure at a dose of 8 tons and mineral fertilizers, N84P30K48), productivity increases to 4.3 t/ha of grain units, and humus content increases to 4.1% (or 7.8%).
