Description :
Greyzems (Grey Forest Soils) are zonal soils of the forest-steppe, in Russia geographically situated between the (Podzo) Luvisols of the southern taiga forest and the (Luvic) Chernozems of the steppe. Three Greyzem profiles, presently under forest, and developed on loess-like mantle loams of Late Weichselian (Valday) age in the northern forest-steppe zone of the East European plain (Middle Russian Upland) were described and sampled near Puschino, some 100 km south of Moscow. Micromorphology, particle size data, chemical data and clay mineralogy were studied. The results lead to conclude that greyzems are polygenetic.
