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).
