Description :
The aim of this study is to evaluate the effectiveness of M. aquifolium strips on soil erosion control under various bio-physical conditions with the use of the Revised Morgan–Morgan–Finney model (RMMF). After calibration the model showed erosion to be transport limited process for all M. aquifolium plots and a detachment limited for the bare soil control plot. The model was then used to predict surface runoff and soil loss for various soil types, slope angles and cultivations with and without M. aquifolium strips. The study indicated that the presence of M. aquifolium strips substantially reduced the soil loss rate on all studied crop fields. For steeper slopes with M. aquifolium strips the model predicted a lower soil loss rate than for gentle slopes without strips.
