Soils, composed on slope deposits, mutually generate an integrated system of nutrient and energy interactions, which reflects the soil production process with a high level of variability of soil properties. Hydric potential of slope deposits represents a direct interconnection to hydrological system of catchment through the presence of ground water table and at the same time it can significantly influence the soil water content. The depth of soils and slope deposits is an important quantitative attribute, being necessary to determine water and nutrient storage. The interpretation and calibration of the soil resistivity measurements compared to different sources of literature and as well as to several destructive and non-destructive methods, offer some methodical base for next research of soil hydrology. The new scale of soi I resistivity allows us to identity such phenomena as coarse-textured material, ground water table and capillarity fringe, to estimate total soil depth and to evaluate spatial variability of these properties. The electrical resistivity tomography modifies spatial scale of soil processes and contributes to clarity water and nutrient balance of forest ecosystem. This study provides some bases for application of intensity-capacitive approach, which assesses ecological-productive and regulative potential of forest soils in absolute values.
