ROOT AND CROP RESIDUES IN THE SOIL WITH FORAGE CROPS

Abstract

When using the land during the year, sowing soybeans for grain after four-component (triticale + rapeseed + green peas + oil radish) winter catch crops, the number of feed units was 13380, the amount and quality of protein increased, the bulk soil mass decreased by 0.05-0, 03 g / cm3, and the water permeability increased by 20.9 mm / h. When sowing soybeans after one type of food crops in 0-30 cm soil layer, the humus content increased from 1.103% to 1.116%, and when sowing soybeans after four types of catch crops it increased from 1.145% to 1.165%, the total amount of nitrogen from 0.121% to 0.141%, the humus content after four types of soybean catch crops increased by 0.042-0.049%, and the amount of nitrogen by 0.020%.
