Evaluation of soil erosion using common direct methods is costly and time-consuming. Therefore there is a need to develop suitable indirect methods for this purpose. One of the alternative methods that can be used is measurement of soil magnetic properties. The aim of this study is to evaluate the suitability of measuring magnetic susceptibility in assessing soil degradation due to erosion at two locations with different soil types. After the application of an empirical model to predict the values of magnetic parameter after erosion of soil material from the surface, the amount of soil loss is estimated. The first site is located in Southern Moravia. Dominant soil unit was Chernozem that was gradually degraded on steep slopes to Regosols. Second study site is in Central Bohemia, where dominant soil unit is Luvisol, gradually transformed to Regosols due to soil erosion.
