This paper aims at assessing the impact of crops on water erosion parameters. Water erosion is the most common cause of damaging agricultural land in the Czech Republic. This is due to the large average slope of land and the prevailing soil types. The field trial was based on a site with an average slope of 5.4°. The primary objective was to assess the effect of the crop on the surface runoff and soil loss. The crops cultivated in the experiment were winter wheat, rape, potatoes, corn and oats (conventional tillage for all variants). Black fallow was used as the comparative variant (without vegetation). There is a light cambisol on the experimental field. To assess erosion, the method of microplots was used. The physical properties of the soil were also evaluated. The results show the risk of growing wide-rows crops (potatoes, corn). The soil loss in these crops was similar to the variant without vegetation.
