Soil redistribution rates calculated by a 137Cs conversion model (Graph) show maximum erosion rates of 37 t ha-1 yr-1 at the summit and shoulder position of the hillslope and maximum deposition rates of 29 t ha-1 yr-1 at the footslope/valley position of the hillslope.
These results correspond well with catenary soil development and show a good agreement with average soil erosion rates of 35 t ha-1 yr-1 predicted by the WEPP-model.
When simulating the effect of land management practices as prevention strategies, results indicate that mulching/residue addition and minimum tillage can reduce average soil loss by 20 % and 30 %, whereas the construction of stone rows can reduce soil loss by up to 90 %.
Considering the high erosion risk and the low nutrient status of the soils, conservation techniques should have both a physical-mechanical function to control runoff and soil loss and a biological-agronomical impact to restore soil nutrients and to improve soil fertility.
A combination of both measures would be the most appropriate option to meet the concept of sustainable land management.
