Fig. 2. Summary of N gas production. Total denitrification (N2O + N2 by C2H2 inhibition) is represented by the height of bars. The N2O production (in the absence of C2H2) is represented by the shaded area. The N2 production is inferred by difference (unshaded area). Even though total denitrification did not differ significantly between moisture histories for cropped soils, the short-wet incubations produced significantly more N2O and less N2. Error bars represent standard error of total denitrification and N2O production (n = 3).
