Fig. 2. Cumulative (a) N₂O-N flux and (b) N₂–N flux from the large soil cores after 85 d versus the initial soil pH. FC = field capacity, SAT = saturated. Error bars represent the standard error of the mean. (N = 3). The dotted line represents linear regression of soil pH and cumulative N₂ flux (P < 0.05, r² = 0.26).
