Abstrakt: Water erosion significantly affects soil properties, yet comparative studies between different soil types are limited. This study examines the impact of erosion on the physical, chemical, and biochemical properties of Chernozems and Cambisols in the South Moravian and Vysočina regions of the Czech Republic. We combined field sampling, laboratory analysis, and geospatial modeling to identify erosion, transition, and deposition zones on slopes. Soil samples were collected from these zones in both soil types and analyzed for particle size distribution, organic carbon content, humus quality, stability of aggregates, pH, nutrient levels, enzyme activities, and glomalin content. Chernozems showed more pronounced differences between the erosion and deposition zones, particularly in organic matter content, nutrient levels, and enzyme activities. Cambisols exhibited different patterns, with less pronounced differences between the zones, except for humic substances and cellulase activity. Chernozems had higher carbonate content and pH in erosion areas, while Cambisols showed an opposite trend. These differences relate to both substrate and slope shape: concave–convex for Chernozems and convex to convex–concave for Cambisols. The findings highlight the importance of considering soil type and topography in erosion studies and have significant implications for tailored soil management and erosion control strategies in different agricultural landscapes.
