Range of nitrous oxide emission was measured in controlled conditions after application of pig slurry. Both measured emission and 15N deficit went beyond 20% of total applied nitrogen. It showed that models of nitrous oxide emission can be improved with a better knowledge of the frequency of favorable pedo-climatic conditions.
