Table 1 Mean fluxes in μg N2O-N m−2 h−1 (standard deviations given in brackets) for the eight weeks of the laboratory experiment for three nitrogen levels (Low = 10 kg ha-1, Normal = 50 kg ha-1 and High = 150 kg ha-1).

From: High nitrous oxide emissions from temporary flooded depressions within croplands
