- Аннотация: During the laboratory experiment, devoted to studying of the process of vertical migration 60Co radionuclide/in water-saturated soil samples of disturbed structure and the same initial bulk density, there were obtained the values of effective diffusion coefficients ( Deff60Co) for 8 different types, species and varieties of soils. There was noted a significant variability of Deff60Co for investigated soils due to different soil characteristics. To assess this influence a statistical approach has been used, where edaphic factors representing the most important characteristics of the soils acted as independent variables (predictors), and the dependent (resulting) variable was Deff60Co. Based on the study of the dependence between the main physico-chemical soil properties and the magnitude of effective diffusion coefficients ( Deff60Co) the selected physico-chemical characteristics of soils were ranked by degree of influence on the value of the dependent variable: pHKCl > (fr.<0.01) > Corg. There was also identified the contribution of each of the selected indicators of soils state (independed variables) in varying of Deff60Co. The contribution for pHKCl, (fr.<0.01), and Corg was, respectively, 36,32; 27,90 and 17,08 %. During the experiments revealed a particularly strong increase in the Deff60Co for soils with high content of humus in conditions of excessive moisture.
