The aim of the project is to reduce nitrous oxide (N2O) and ammonia (NH3) emissions (N-emissions) in field vegetable production, mainly from crop residues with a high nitrogen (N) content. Removal of residues from the field can reduce these N emissions, but further processing of crop residues is challenging. A novel approach is to upgrade crop residues through composting, ensiling, and digestion, and then return them to the field as fertilizer. This upgrading offers considerable potential to recycle N contained in the residues and to use it specifically for subsequent crops, thus reducing the use of mineral fertilizers. The project investigates the removal and valorization of crop residues in white cabbage cultivation (Brassica oleracea L. convar. capitata var. capitata f. alba). In this context, N emissions are quantified for all upgrading methods and in all process stages in order to calculate an N emission balance, and to be able to exclude N relocation effects. Emission measurements under controlled conditions help to determine the influencing factors and thus allow extrapolation on a national level.
