Research of the influence of the primary soil tillage, application of organic and mineral fertilizers on the indices of soil structure and its erosion resistance by the example of sod-podzolic light loamy soils with degree of erosion was realized in the conditions of the Republic of Belarus. Research results proved that sod-podzolic light loamy soils could be characterized by low erosion resistance. The increasing of soil erosion class caused the lowering of its resistance to soil losses (water denudation) and washout. Application of beardless chisel soil tillage in combination with organic and mineral fertilizer mixture for the cereal grass crop rotations made it possible to increase soil erosion resistance. Subsurface soil tillage made it possible to increase the content of water-stable aggregates on 5,7-9,5%, their average weighted index from 0,7-0,9 up to 0,9-1,2 mm and the coefficient of water stability – from 0,42 up to 0,48-0,70, ground erosive velocity – on 1,0-1,5 cm/s. Application of mineral and organic fertilizers promoted the acceleration of crop growth and development, including the root mass as well the increasing of extra intake of plant (root and afterharvesting) residues by soil
