Abstract

The processes of the overgrowing of abandoned soils by native vegetation have been studied. It has been shown that in arable soils after their removal from agricultural use and the development of secondary forest in their place, with an increase of forest renewal period, starting from 20 years from the moment of reforestation, positive trends in their humus state take place. It is revealed that it is possible to completely restore their humus state within 80—100 years, which is reflected in the full compliance of the OM parame ters with those of automorphic Sodpodzolic soils of the Center of the Russian Plain, i.e., the level of accumulation and the share of carbon in organic and mineral-mineral fractions in the total accumulation of carbon in the soil and in the value of the ratio (CLF/CClay).

Keywords

soil organic matter, reforestation, granulo- dencymetric fractionation, light fractions.
