Abstract

Effect of the initial degree of reclaiming on the development of modern soil-forming processes in long-fallow agro-sod-podzolic loamy soils, which led to a change in their agrochemical indicators, was established on basis of the data of many years field experiment. It is shown that the overgrowing of agro-sod-podzolic soils of different levels of reclaiming led to the differentiation of postagrogenic arable horizon into two sublayers. The sod process of soil formation is superimposed on its upper part (0-10 cm), leading to an increase in the content of organic matter and the amount of exchange bases in it. At the lower (10-20 cm) – podzolic process, which causes a decrease in its humus content and an increase in acidity. Increased and high initial reclaiming accelerates the process of differentiation of the postagrogenic horizon into sublayers. The levels of reclaiming of the arable horizon created in previous years were preserved even in the third year of overgrowth.
