Changes in the Agrochemical Parameters of Fallow Lands Located in the Transit Route of Material and Energy Flux at Different Times of Their Overgrowth

摘要

It has been shown that, when the overgrowth time of agrosoddy-podzolic soils increases, the soil acidity increases, the content of total exchangeable bases decreases, and the differentiation of the plow layer by the content of humus occurs due to itsincrease in the 0- to 10-cm layer and decrease at the bottom. It has been proposed to use the degree of humus differentiation in the plow layer for the determination of the period of plowland overgrowth.
