Technologies and Technical Means for Anti-Erosion Differentiated Soil Treatment System

Abstract

This paper highlights the necessity of system modification of the main soil slopes processing by developing new technologies of processing eroded soils and technical means to protect a soil from wind and water erosion, reduce processing energy costs, improve moisture accumulation and preservation, and increase the aggregate productivity. An improved differentiated system of slopes soil tilling is proposed, including a crest-stepped ploughing with complete alternation (at 180° within the range of own furrow) and incomplete turnover of the layers and mouldboardless two-tier tilling. During the first year, a crest-stepped ploughing was carried out on slope fields affected by water and wind erosion. Thus, stratum’s subsurface layers are strip loosened. To implement this technology, an improved plough for crest-stepped ploughing developed on the basis of a stepped plough for furrowless smooth tillage is proposed. The rotation was carried out with mould boardless two-tier soil tilling by a ripper with inclined posts. Further, it is recommended to develop and implement combined machines able to simultaneously conduct mould boardless and mouldboard soil tilling, strip subsurface loosening, fertilizer application and other manipulations to prepare soil for sowing and the sowing per one passage of the unit to protect soil from wind and water erosion.
