Topography impact on soil erosion and crop yield

Abstract

The density of valley and gully network controls to a considerable extent slopes length, steepness and profile and therefore soil erosion. Inadequate agricultural technique constantly used under conditions of deeply dissected topography resulted in enhancement of erosion processes. Gullies and eroded soils form components of agricultural lanscaped of Kursk region and impart an ecological stress to the landscapes. The productivity of agricultural landscapes is low within the zones of high ecological stress.
