Growing system with intermediate crops and smart management of tops for effective climate benefit

The purpose of this project is to gain new, broad and in-depth knowledge of how intermediate crops and smart handling of straw and nitrogen-rich crop residues in our cultivation systems can contribute to an effective climate benefit. By using intermediate crops (catch crops, cover crops) in the crop rotation, several important fertility-increasing factors can be affected, such as increased soil organic carbon content, erosion protection, reduced leakage of plant nutrients and control of weeds and plant diseases. For society, the cultivation of intermediate crops therefore means a reduced environmental burden and that crop cultivation can be carried out sustainably. Tops and nitrogen-rich crop residues make a valuable addition to the soil's organic carbon content, but risks with nitrous oxide emissions need to be taken into account in this context, in order to obtain optimal carbon storage and minimal nitrous oxide emissions.
