COEFFICIENTS OF MOISTEN OF SOILS OF BELARUS AND YIELDS OF AGRICULTURAL CULTURES

Abstract

Coefficients of moisten is a relation of actual stores of available water to optimal stories equal 85% of a field moisture capacity in arable layers. They were determined on field collective farms for loamy, sandy loam and peat soils as indicators water supply plants. In overwhelming cases they equal 0.6-0.7 for all period vegetation fluctuating from 0.2 to 1.0. It is evidence about water deficiency for plants. Culture yields was the following: winter wheat - 1.9-2.5 t/ha, barley - 1.7-4.5 t/ha, potato - 17-29 t/ha on background of differential rates fertilizers.
