Soil and Eco-Economic Substantiation of the Need for Switching to the Adaptive-Landscape Systems of Agriculture in the Krasnodar Krai

Abstract

The climatic, soil, ecological and economic features of the natural landscapes in the Krasnodar Krai were analyzed. The land structure of cultivated land in Western Ciscaucasia was given; the current state of soils in the Krasnodar Krai was analyzed. The changes in the content of humus in the arable layer over the century were considered. The qualitative state of agricultural lands, such as the susceptibility to erosion, the content of humus, and indicators of the nutrients balance in the soil was shown. A conclusion the existing zonal agriculture systems do not use the landscape diversity of the region was drawn. The need for switching to the adaptive landscape system of agriculture was substantiated. Using the GIS technologies, the boundaries of the natural landscapes in the Krasnodar Krai and the areas of agricultural land was determined by types and the degree of the manifestation of erosion processes. An eco-economic assessment of the field crop rotations adapted to the natural landscape by cultivated lands was made.

Geoecological Assessment of Treated Soils

“…С целью предотвращения разрушения почв в 1980-е гг. в нашей стране появляется зональная система земледелия, которая, однако, не учитывает полностью ландшафтные особенности регионов и не может обеспечить сохранение земель в процессе их сельскохозяйственного использования [4]. Принятая в 1992 г. стратегия устойчивого развития человечества и биосферы послужила толчком для экологизации в земледельческой науке и разработки концепции адаптивно-ландшафтного земледелия, впервые предложенной В.И.…”
