The following report introduces a farm with long-term experiences in cultivating catch crops in order to reduce soil erosion and nitrogen leaching. Apart from winter hard (very important) catch crop mixtures, green rye and under-sowing in maize are used.
“If you want take advantage of these mixtures the catch crop cultivation has to be done properly. The main crop can only profit if the catch crop is well-established resulting in an optimal N-fixation, sufficient erosion control and deep rooting. Just to do the minimum in order to comply with the greening requirements achieves nothing.”
