The structural-aggregate composition of ordinary chernozem under winter wheat depending on soil treatment methods

The authors studied the influence of agricultural activity on agrophysical factors of fertility in particular on the structural and aggregate composition of the soil. The content of agronomically valuable fraction of 10-0.25 mm during the growing season of winter wheat on predecessors pure steam and corn 74,82-81,19%. Indicators of the soil structure coefficient of ordinary Chernozem indicate that both predecessors provided excellent soil condition.
