Comparison between the seasonal temperature relationship of in situ measurements for soil C emissions and of the temperature sensitivity of C mineralization data of spatially paired samples expressed as Q10 values for the control-irrigated treatment (I) and the fertilized-irrigated treatment (FI), respectively (mean and standard error in brackets of n = 2 field replicates × 3 subsamples = 6 samples, because there were no significant differences between field replicates). Field temperature measurements were made at 10 cm depth
| Q10 for C mineralization | |||

| I | 4.1 (0.5) | 2.8 (0.2) | 2.8 (0.2) |
| FI | 4.8 (0.6) | 3.4 (0.1) | 3.6 (0.3) |
