Biogenic nitrous oxide (N2O) from nitrification and denitrification in agricultural soils is a major source of N2O the atmosphere, its flux changes significantly with soil moisture condition. However, quantitative relationship between production different pathways (i.e., vs. denitrification) content remains elusive, limiting our ability predicting future emissions under changing environment. This study quantified rates various conditions using laboratory incubation combined literature synthesis. 15N labeling approach was used to differentiate eight contents ranging 40 120% water-filled pore space (WFPS) study, while 80 groups data 17 studies across global were collected Results showed that as increased, first increased then decreased, peak occurring 95% WFPS.

Abstract Nitrous oxide (N 2 O) is the third important long‐lived greenhouse gas next to carbon dioxide and methane croplands are considered biogeochemical hotspots of soil N O emissions. To reduce other emissions, climate‐smart agricultural practices including biochar application have been applied. Many studies conducted with but results from these not conclusive. address this issue, meta‐analysis, a quantitative review that synthesizes multiple independent studies, has widely used. The different meta‐analyses also differ seldomly evaluated. In study, we evaluated on effects A grand mean response ratio (RR) was further proposed estimate an overall effect impacts experiment setting, properties soil, practices. We found 18 meta‐analysis papers were published between 2014 2022. Sample size (publications or experiments) varied less than 30 more 1000, sample 275. RR calculated in all except one. While four did find significant others reported reductions magnitude ranged −10.5% −54.8%.
