Microelemental Composition of Zonal Soils in the Central Chernozemic Region

摘要

Microelemental composition of zonal soils in the central chernozemic region has been analyzed.It is shown that the distribution of microelements in the profiles of gray forest soils follows the eluvial-illuvial pattern.The distribution of microelements in the profiles of chernozems is affected by the processes of humus formation,humus accumulation,biogenic accumulation,and,to a lesser degree,leaching,illuviation,and lessivage.Microelemental composition of zonal soils reflects genetic features of particular soil subtypes.
