The results of the study of peat soils organic substance structure with various peat ash content are given. Contents of active organic substance and carbon of microbial biomass in peat and boggy soil with 20% peat ash content is 3.0-3.5 and 1.6-1.8 times higher correspondingly, than thus in peaty-gley soil with 70% peat ash content. At peat and boggy soil with low peat ash content Cs137 transition into hay is minimal. 14 times higher than at peaty-gley soil with 70% peat ash content. Application of fertilizers at peat and boggy soil reduces Cs137 transition factor 4.7-6.4 times if compared to peaty-gley soil (2.1-4.7 times). Close positive interconnection between Cs137 transition factors from soil into the plants and organic carbon soil contents, absolute contents of potentially mineralized carbon and mineralization degree.
