AGROMELIORATION: CULTIVATION OF SIEROZEM SOILS

Abstract

Scientists of the Agricultural Experimental Station of Cotton and Melon Growing conducted research to prevent the progressive soil density, based on the technology of basic soil cultivation, - deep loosening to a depth of 50-55 cm in order to destroy the plow sole and improve the agrophysical properties of the soil. The main purpose, which is the destruction of the plow sole of the soil. In the conditions of gray earth soils, carrying out the main cultivation to a depth of 40-50 cm, in combination with deep tillage to a depth of 50-55 cm, the bulk soil mass is formed within the optimal level and is 0-10 cm in the layer, 1.26 g / cm³, 10-20 cm - 1.28 and 20-30 cm - 1.29 g / cm³. The most loose soil structure is observed with longline plowing to a depth of 40 cm in combination with loosening the soil to a depth of 50-55 cm. The deepening and cultivation of the arable layer is one of the urgent tasks of agriculture. The optimal arable layer allows accumulating more moisture, organic matter, increasing the zone of active activity of soil microorganisms, the availability of nutrients and agrophysical conditions.
