Fig. S1. Effect of temperature, soil moisture and fertilizer concentration on nitrous oxide emission rates due to nitrification (lines) and on potential nitrification activity (bars). Key: % of WHC represents the percent of the soil's maximum water holding capacity. Fertilizer treatments are denoted as LF, MF and HF and represent low, moderate and high fertilizer concentrations (0.05, 0.1 and 0.3% of fertilizer, respectively). Rates were calculated per gram dry soil (gds). Error bars are 95% confidence limits.

Fig. S2. Path diagram of the hypothesized models analyzed using path analysis for potential nitrification activity and. Direct effects are designated as A, B, C and D and indirect effects as E---B, F---C, G---D. Path coefficients for the latter are written on the first arrow and letter only, but represent the complete path. NH3=ammonia concentration, PNA= potential nitrification activity, SAC3a=scaled abundance of cluster 3a, SAC9=scaled abundance of cluster 9, SAC10=scaled abundance of cluster 10.
