Soil successions of carbic podzols (arenic) and umbric podzolsof sand forest steppe at change of forest-forming rocks

The article presents the data of ecological-soil survey of carbic podzols (aerenic) and umbric podzols of sandy pine forests of the Kursk agglomeration. The data on the transformation of morphological, physical and physicochemical properties of the studied soils in the succession series "pine forest - mixed forest - broadleaf forest" are presented. It has been established that when the monodominant plantations of Scots pine are replaced by deciduous species, the soil-forming processes change - podzolic to sod. The settling of deciduous species in pine plantations gradually leads to attenuation of the podzolic process, the development of processes of accumulation of humus and mineral nutrients in the soil profile, which contributes to an increase in the ecological stability of azonal carbic podzols (aerenic) and sandy umbric podzols in the conditions of the forest-steppe zone.
