DYNAMICS MOISTURE RESERVES AND THEIR AVAILABILITY PLANTS IN TYPICAL BLACK SOIL BY VARIOUS TILLAGE SYSTEMS

In the article presents the results of studies of the dynamics of productive moisture in typical black soil and their availability to plants in the main phases of development of corn. Deep non plow tillage form the largest average moisture reserves of the soil layers 0-100 and 0-200 cm, provides good water permeability of the upper layers to form a reserve of moisture in autumn and winter, high availability of water, continuous flow through the capillaries to the roots plants and their rational use in the growing corn
