文摘

The meta-analysis included 38 studies (422 N2O emission factors in 12 countries). The weighted-REML showed higher synthetic-N emission factors with better N2O coverage. We propose a global emission factor for organic inputs of 0.57 ± 0.3% of N applied. We encourage the use of three identified N2O risk classes of organic amendments. Emission factors were 2.8 times greater in fine- than in coarse-textured soils.
