abstract:
In the Central Sudety region two toposequences of soils with average slope decline of 13.6% and 9.5%, elevation of 450-500 m a.s.l., represented by lithogenous, limestone soil and autogenous, brown acid soil were analyzed. In order to determine the intensity of water erosion, installations for measuring the amount of washed away soil were placed at both the sites. In the soil samples, grain size distribution, macronutrients content and salinity were determined. The substantial differences in grain size distribution in samples of material forming accumulative levels on the slope as well as differences in macronutrients content were found.
