The modification of ecopedological indexes under the long term antropogenic impact

Abstract

This work is dedicated to the study of ecopedological indexes in different coenosis - steppe; agrocoenosis - arable field, autumn wheat, single-crop corn system (60 years), fallow soil (60 and 100 years), its modification estimated under different anthropogenic influences and agricultural management level and founding of diagnostic indexes in complex evaluation of anthropogenic impact. It was established that soil degradation impact is directly dependent on the level of agricultural management; the studied coenosis soils are significantly modified under anthropogenic impact, and the coenosis near old villages are strongly degraded. The physical degradations (structure modification, bulk density, adherence) prevail. The adherence can be used as diagnostic ecopedologial index for the appreciation of anthropogenic impact level on agro-ecosystem.
