Davydenko G. 3.The soil-protecting and agronomical efficiency of against erosion complex in north-eastern Forest-steppe of Ukraine

3. Dissertation is devoted the study of the soil-protecting and agronomical efficiency of against erosion complex which includes the system of agriculture with contour-melioration organization of territory, one of basic elements of which are soil-protecting measures of permanent action as against erosion hydro technical buildings and field-protecting forest bars, and also mini till soils and soil-protecting crop rotations, saturated long-term herbages. Found out the positive operating of the protracted application of this complex on diminishing of erosive processes and improvement of agro physical and agricultural chemistries indexes of chernozems eroded on earths of slopes.The picture of influencing of elements of contour-melioration organization of territory is deep, mini method of till, fertilizer and reared cultures on diminishing of losses of soil fromwashing off that allows forecasting application of measures on the improvement of the existent systems of agriculture on earths of slopes.
