a Nitrification rates. b N2O production rates during nitrification. Four scenarios were constructed: the ambient control (400 μatm/pH 8.1, blue solid bars), the acidified group (800 μatm/pH 7.8, red solid bars), reduction of pH only (400 μatm/pH 7.8, red open bars), and increase of pCO2 only (800 μatm/pH 8.1, blue open bars). Different lowercase letters (a, b, c and d) above the columns indicate significant differences among the four scenarios (P < 0.05). Error bars represent SD (n = 3 biologically independent samples), and dots are corresponding data points of the replicates. Significant differences were determined via one-way analysis of variance (ANOVA). Source data are provided as a source data file.
