COMPARATIVE CHARACTERISTICS OF THE MINERALOGICAL STATUS OF CHERNOZEMS TYPICAL ON THE COVERING SEDIMENTS OF THE WATERSHEDS OF MOLDOVA AND THE CENTRAL RUSSIAN UPLAND

Abstract

Comparative study of the mineralogical status of silicate part of the typical chernozems on the covering sediments of the watersheds of Moldova and the Central Russian upland showed that both the soil in composition and the content of primary and clay minerals are very close. They are also close according to the changes occurring in them processes of weathering and soil formation. Changes develop in the eluvial type. A significant excess loss of clay minerals in the Kursk chernozem over the loss of the Moldova's chernozem is due to the gradual relief of the soil-forming rocks in Kursk chernozem up on the profile. The study showed that the method of mineralogical analysis and the method of assessment of the mineralogical status of soils used in Moldova are also applicable on the chernozems of the Russian plain.
