Effect of soil type and overgrowth time on agrochemical parameters of fallow lands located along the accumulation trend of material–energy flow

Abstract

It has been shown that changes in agrochemical parameters of fallow lands depend on the type of soil and the time of overgrowth. A gradual acidification of the postagrogenic layer, its differentiation into two sublayers by the contents of humus and total exchangeable bases, and a decrease in the content of mineral nutrients are observed in overgrown agrosoddy-podzolic soils. In agrogray soils, these processes are less intense.
