Structural-aggregate composition and soil density depending on the main processing method and predecessor of winter wheat on erosion-dangerous slope

The article presents the results of research to establish the influence of different methods of basic tillage and predecessor of winter wheat on the structural and aggregate composition and density of ordinary chernozems in conditions of erosion-dangerous slope. It was found that the use of chisel treatment had a beneficial effect on the structure of erosion-hazardous black earth soils, increasing not only the coefficient of structure, but also reducing the density, which contributed to an increase in soil resistance to water erosion. The highest structural coefficients of ordinary Chernozem in terms of erosion slope 3.42-4.85 were designated by the predecessor of pure steam.
