Fig. 2. Nitrous oxide flux partitioning for comparison between organically and conventionally managed soils collected in July and at 23% WFPS. Soils were incubated under ambient air, then under 10 Pa C₂H₂, then under 10 K Pa C₂H₂ at field moisture and temperature to determine sources of rates of N₂O emissions and N produced during denitrification. Mean (n = 10) ± SEM are shown for each treatment and incubation.
