Summary

Klimabelastning bør indgå i vurderingen af dyrkningssystemers bæredygtighed. Vi undersøgte udledningen af drivhusgasser under opbevaring og efter udbringning af gødningsprodukter til økologiske sædskifter: Afhøstet kløvergræs som blev ensileret eller komposteret, og plantebiomasse som blev afgasset sammen med gylle. Både afgasset gylle og ensilage af kløvergræs viste positive resultater mht. merudbytte og klimaeffekt.


Summary translation

Climate impact should be taken into account when evaluating the sustainability of cropping systems. We determined emissions of greenhouse gases during storage and after field application of fertilizer products for organic crop rotations: Grass-clover cuts that were either ensiled or composted, and plant biomass which was co-digested with slurry. Both digestate and grass-clover silage showed positive results with respect to added crop yield and climate impact.
