Evaluating vegetated buffer zones for phosphorus retention in cereal and grass production

Summary in the original language of the document

The buffer zones seem to be effective to stop erosion and trap particle bound P in surface runoff from the autumn ploughed clay soil. On pastures, the buffers are not so important, if P fertiliser is not surface applied and the grazing intensity is not too high. However, the high DRP loss to surface runoff may be a real problem on grass fields in spring. The buffers are not able to uptake nutrients in early spring when the runoff is highest.
