Postagrogenic migrational-mycelial chernozems of abandoned fields of different ages in the southern forest-steppe of European Russia

The restoration of the properties and morphology of migrational-mycelial (typical) chernozems under the impact of natural vegetation successions on abandoned fields of different ages (from 1 to 60 years) was studied in the forest-steppe zone of the Russian Plain. The stages of the postagrogenic transformation of the chernozems were identified, the rates of restoration of the particular soil properties were determined, and the time required for the restoration of the properties of virgin chernozems was estimated.
