Abstract : The case study is devoted to the agroecological peculiarities of the eroded soils fertility taking into account their genesis and morphology. The researched soils are located on the slopes of different exposure in the subzone of ordinary black mollisols. The laboratory and field observation of the eroded soils was carried out on the base of training farm ”Samarsky”. The research of quantitative and qualitative composition of physical and chemical qualities in arable soils on the slopes and watersheds was performed. On the basis of it the dependence between the eroded soils fertility and environmental conditions was established. On their genesis, the slope soils are represented by the variety of watershed types of black mollisols. These soils are considered as special more arid soils additionally superimposed with erosion process. They represent genetic forms of intrazonal and zonal types. The humus content in the 0-30 cm layer in the plain amounted to 4.1 %, while decreasing on the northern exposure slope by one third, and on the southern exposure slope – twice. The qualitative humus change was observed: the humic acid content decrease when insignificant change of fulvic acids.
