Erosion factors of a part of Western Serbia, that is, different precipitation amounts and intensities, influencing humus-silicate soil formed on the serpentine, with an 18% inclination toward the northwestsoutheast at the altitude of 300 m, enabled quantitative runoff amounts and soil losses of the fallow and of autochthonous vegetation plot to be defined over a three-year study period. Throughout the trial, the mean annual runoff from the fallow plot amounted to 28.75 l·m-2, and erosion losses of the soil were 2648.42 g·m-2. Mean annual runoff and soil losses from the autochthonous vegetation plot were 12.37 l·m-2 and 0.98 g·m-2, respectively. The total variability of runoff from the fallow plot due to precipitations was 28.1% and that from the plot under autochthonous vegetation was 0.2%. The total variability of soil losses from the fallow plot, due to precipitation, was 43.6% and that from the plot under autochthonous vegetation was 49%.
