The dependence of the content of 137 Cs-forms in sod-podzolic sabulous soils of different degree of humidification on the basic soil tillage is presented. Structure (in %) of plant available 137Cs in automorphic and semi-hydromorphic soils is shown. The influence of soil tillage type on 137Cs content is analyzed per 2007-2008. Content (in %) of plant available 137Cs in automorphic and semi-hydromorphic soils during moldboard plowing, beardless plowing, surface disc plowing and minimum tillage is evaluated. In sod-podzolic sabulous soils with 137 Cs pollution density which equals to 13-15 Cu/km2 the content of the accessible for plants forms (water-soluble, exchangeable, mobile forms) makes in average 9-11%; of those inaccessible (not exchangeable, fixed) – 89-91%. It is established, that the degree of the hydromorphic feature in sod-podzolic sabolous soil influence the content of accessible forms of 1376cs in its top layer. The chisel tillage and the minimum tillage make it possible to decrease the accessible 137Cs connections by 2-4%.
