THE IMPORTANCE OF FERTILIZERS IN INCREASING THE PRODUCTIVITY OF REPEATED CROPS SOYBEAN, POTATO AND SOIL FERTILITY
Abstract
The article presents data on the effects of repeated soybean and potato crops on the agrophysical and agrochemical properties of the soil and the crop yield in the lower part of the soil, where the particles washed from the slopes are sitting (accumulated) after winter wheat, in the conditions of typical gray soils subjected to irrigation erosion.
