Sheet wash studies using soil profiles analysis (Kursk region)

Abstract

Sheet wash studies were carried out in the Kursk region using soil profiles analysis, eroded layer thickness being taken as indicator of the wash processes. A variability of humic horizon thickness under natural conditions has been established for chernozems and gray forest soils. The differentiated standard for non-eroded soils is proposed, which has been developed for individual types and sub-types of soils which occur on various topographic elements differing in orientation. A map of soil erosion degree id compiled for the Kursk region.
