The minimum transition of radionuclides from sod-podzolic loam sandy soils in plants is defined by degree of saturation the bases in the range of 75-90%. The minimum accumulation 137Cs by agricultural crops is marked at the content of exchange calcium of 65-80%, magnesium of 5-20%, 5-6% potassium from capacity of cation exchange and 90Sr - 80%, 5%, 5% accordingly. Regulation of content of exchange and mobile cations in soil, on the polluted farmlands, is necessary to spend by liming of soils and application of potash fertilizers on the basis of data of agrochemical inspection taking into account concrete type of crop rotation
