FIELD: agriculture. SUBSTANCE: method involves selecting catena from watershed level to erosion basis on territory under investigation; separating key zone on catena; providing soil openings thereon and drilling holes up to confining bed with separating aeration zones; taking soil samples in layers; sampling soil forming rocks of aeration zones and evaluating structure of soil cover by components of soil openings of key zone, soils and soil forming rocks of bore holes in aeration zone. EFFECT: increased precision in evaluating soil covering structure and, as a consequence, improved ecological and economic usefulness of complex of soil amelioration arrangements. 4 dwg, 2 tbl
