THE SOIL ВIOLOGICAL ACTIVITY UNDER WINTER WHEAT IN VARIOUS LINKS OF SHORT-ROTATION CROP ROTATION IN THE CONDITIONS OF THE DANUBE STEPPE

Abstract

The studies were carried out in a stationary two-factor experiment on ordinary chernozem. It has been proved that during 3 years the conducting of the dump-non-dumping system of the main tillage provided an increase in the decomposition capacity of fiber and, accordingly, the biological activity of the soil. Considering the effect of various short-rotation crop rotation links on the level of cellulose-destructive activity of the soil in the winter wheat field, a certain tendency to increase the biological activity indicators in the grain rotation link with the rotation of corn crops for grain - peas - winter wheat, as compared to the oilbearing link with alternating sunflower - peas - winter wheat was noted in the experiment.
