Yg. Chendev, AGROTECHNOGENIC TRANSFORMATION OF DARK GRAY FOREST SOILS IN THE CENTRAL FOREST-STEPPE ZONE DURING THE LAST 200 YEARS, Eurasian soil science, 30(1), 1997, pp. 5-15
The virgin and arable soils that replaced the forest areas in the sout
h of the Central Russian forest-steppe were studied. The trend of agro
technogenic evolution of dark gray forest soils to podzolized chernoze
ms through the stage of gley conditions was revealed. The period of th
e evolutionary transformation is estimated at more than 200 years.
