THE DEPENDENCE OF THE CONTENT OF 137СS-FORMS IN SOD-PODZOLIC SABULOUS SOIL OF DIFFERENT DEGREE OF HUMIDIFICATION ON THE BASIC SOIL TILLAGE

Abstract

The dependence of the content of 137Сs-forms in sod-podzolic sabulous soil of different degree of humidification on the basic soil tillage. In sod-podzolic sabulous soils with 137Cs 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 sabulous soil influences the content of accessible forms 137Cs in its top layer. The chisel tillage and the minimum tillage make it possible to decrease the accessible 137Cs connections by 2-4%.
