摘要

When N_2O- and CH_4-emissions of anaerobically digested (AD) cattle slurry are calculated, the application of the AD slurry to grassland should be taken into account. Therefore, the emissions from untreated and AD cattle slurry after surface application and injection into grassland were investigated. Differences in N_2O-emission of untreated and AD slurry after injection seemed strongly dependent of the C/N-ratio of the slurry. After surface application, the emission of N_2O from AD slurry was higher than from untreated slurry. AD lowered CH_4-emission after application, though the effect was not significant.
