Abstract: Water erosion is one of the major factors of soil degradation in the world. Various methods have been developed to prevent soil erosion. One of them is the use of anti-erosion belts on slopes, but it has both positive and negative effects. In order to minimize the negative effects, this study proposes the use of perennial grass in place of the most commonly used trees and shrubs. The paper presents studies on the erosion control effectiveness of a strip planted with Miscanthus x giganteus , established on a loess slope. Surface runoff of water and its constituents and erosion damage was studied on the experimental plot with a separate anti-erosion belt and the control plot. Obtained results indicate the anti-erosion efficiency of the established strip in the context of soil protection from water erosion and surface water protection from pollution, although, in the first years of vegetation, miscanthus has not yet reached the stage of full development. The average surface water runoff relating to precipitation causing the erosive event was 17.1% higher in the control plot than in the experimental plot. The volume of erosion damage in the form of rill erosion was 89.3% higher in the control plot. On the other hand, the volume of erosion damages in surface erosion and patches of deposited silts was lower by 14.7% and 21.6%, respectively. Soil losses from the control plot were 29% higher than those from the experimental plot. Dissolved plant nutrient runoff was also higher from the control plot by: 33.4% N-Ntot, 31.3% N-NH 4 , 42.7% N-NO 3 , 21.6% N-NO 2 , 22.9% P-Ptot, 24.1% K.
