Fig. 3. Nitrous oxide flux and denitrification for intact core incubations at field moisture (40% WFPS) and temperature (–2.5°C) 17 d following T2O manure amendment. Soil cores were incubated under ambient air, then under 10 K Pa C2H2 to determine rates of N2O emissions and N produced during denitrification. Mean (n = 5) ± SEM are shown for each treatment and incubation.
