Results of studies on the sealing of crop residues of leguminous crops with ploughshares

Abstract

The article presents the results of experimental studies of the sealing of crop residues and their distribution over the depth of the cultivated soil layer by known general-purpose ploughshares without ploughshares. The research was carried out in fields with agrophones of winter wheat, chickpeas and winter rapeseed. The plowing of dark chestnut soils located in the steppe soil-climatic zone of the Left-Bank district of the Saratov region was carried out by aggregates K-701+PNL-8-40, K-701+PSK-8 and T-150K+PLN-5-35. As a result of field experiments, it was found out that straw, pollen and stubble are embedded in the soil in accordance with established agrotechnical requirements, more than 80%. Crop and plant residues are located in the bulk in the deep layers of the cultivated soil. Part of the stubble in an inclined position is located in the places where the layers of adjacent passages of the plow hulls meet. The design of the ploughshare-dump surface of the housing does not allow managing the upper organic-enriched soil layer.
