Abstract

Cover crops are a very effective erosion control and environmental conservation technique. When cover crops freeze at the beginning of the winter period, the above-ground biomass becomes less effective in protecting the soil from water erosion, but roots can still play an important role in improving soil strength. Therefore, root density distribution with soil depth and the erosion-reducing effect of these cover crops during concentrated flow erosion were assessed by conducting root auger measurements and controlled concentrated flow experiments with 0.1 m topsoil samples. The results indicate that fine-branched roots are most effective in preventing concentrated flow erosion. After frost, the erosion-reducing potential of some species decreased. Fine-branched root systems (such as ryegrass and rye) are less vulnerable to frost. Ryegrass, rye, oats and white mustard are suitable cover crops to prevent concentrated flow erosion
