Application of Magnetic Susceptibility Measurements for Identification of Technogenic Horizons in Soil Profiles on the Example of the Vistula River Cross-Cut Area

Studies on magnetic properties of soils have been recently applied in the soil environment quality monitoring in relation to basic physical and chemical properties. However, the issue of distribution of ferrimagnetic materials in particular genetic soil horizons, especially in altered soils, has not yet been considered in environmental studies. The main subject of the research was to evaluate a potential of magnetic susceptibility measurements as implements for supporting the soil classification through indication of particular distinctive genetic horizons in the soil profile. The study objects were soils whose formation was strictly conditioned by hydrotechnical regulations in the area of the Vistula River Cross-Cut (northern Poland). It has been demonstrated that the magnetic susceptibility test is an accurate supporting tool in recognition and classification of genetic horizons in a soil profile. The obtained results properly reflected the soil morphological variability and also were good indicators of the presence of lithologic discontinuities of technogenic origin.
