Abstract

When planning conservation agrolandscapes of primary importance auantitafive prediction of soil loss as a result of erosion. Today the area of  ploughland in Kharkov region (oblast) is ecologically tolerable and of 1718868 hectares (63.5% of total land area). Arable lands represented mainly by ordinary and typical Chernozems. The soils are mainly light loams (over 60%) and heavy (about 25%) with the dominance of silt among the separates. Our aim has to compare the data on soil erosion obtained during large-scale survey in 1957-1960,with the data represented  by the maps of soil conservation index (SCI) and the values of potential soil loss by water erosion. The paper contains information on intensity of erosion processes and conceptual models for the long-term  conservation practices in agrolandscapes according to potential soil erosion hazard.
