ABSTRACT
Nitrous oxide (N2 O) is a potent greenhouse gas, and its mitigation is a pressing task in the coming decade. However, it remains unclear which specific process between concurrent nitrification and denitrification dominates worldwide N2 O emission. We snagged an opportunity to ascertain whence the N2 O came and which were the controlling factors on the basis of 1315 soil N2 O observations from 74 peer-reviewed articles. The average N2 O emission derived from nitrification (N2 On ) was higher than that from denitrification (N2 Od ) worldwide. The ratios of nitrification-derived N2 O to denitrification-derived N2 O, hereof N2 OnN2 Od , exhibited large variations across terrestrial ecosystems. Although soil carbon and nitrogen content, pH, moisture, and clay content accounted for a part of the geographical variations in the N2 OnN2 Od ratio, ammonia-oxidizing microorganisms (AOM)denitrifier ratio was the pivotal driver for the N2 OnN2 Od ratios, since the AOMdenitrfier ratio accounted for 53.7% of geographical variations in N2 OnN2 Od ratios. Compared with natural ecosystems, soil pH exerted a more remarkable role to dictate the N2 OnN2 Od ratio in croplands. This study emphasizes the vital role of functional soil microorganisms in geographical variations of N2 OnN2 Od ratio and lays the foundation for the incorporation of soil AOMdenitrfier ratio into models to better predict N2 OnN2 Od ratio. Identifying soil N2 O derivation will provide a global potential benchmark for N2 O mitigation by manipulating the nitrification or denitrification.
