CUMULIC (SEDIMENT) SOILS OF THE CHERNOZEMIC ZONE OF MOLDOVA

Abstract

Cumulic (sediment) soils formed from alluvium with elevated landforms at the foot of the slopes, in ravines, gullies and alluvial fans of the material of the upper layers of soil or material forming rocks. They are formed by a combination of delluvial, colluvial or proluvial of sedimentation with the process of soil formation. Depending on the intensity of soil-forming process, rhythm and rate of accumulation of sediment material, the degree of humus content and grain size, forming a very broad spectrum cumulic (sediment) soils - from less developed to fully-developed, from thin to super, from weakly humus to humus, from sandy to clay.
