In course of a research there was studied the influence of soil processing systems, differing by the way, depth and intensity of influence on a processed layer, and on parameters of biological availability of 137Cs. The research was realized in the conditions of the Republic of Belarus on sod-podzolic sandy soil with different humidity level. As a result of the studied it was revealed, that the degrees of influence of soil tillage and of soil hydromorphism on transition of 137Cs in grain of cultivated crops were approximately identical. Substitution of a traditional plowing by a system of superficial disk processing of soil promoted the increasing of 137Cs entry into products (grain). Systems of subsoil chisel tillage and minimum tillage did not lead to essential increase of radionuclide transition into plants. In technologies of agricultural crop cultivation on polluted with 137Cs sandy soils for the decreasing of power expenses it was possible to use the combination of ways and methods of soil tillage by means of replacement of moldboard plowing by subsoil chisel tillage and the minimum tillage.
