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. By contrast, dominant pathway switched 60 70% Furthermore, synthetic elucidated driver controlling relative contributions production, NH4 + NO3 - concentrations mainly determined each pathway. The treatments broad narrow gradient required capture comprehensive response rate change, essential for accurately emission climate change scenarios.

Nitrous oxide (N2O) is a potent greenhouse gas (GHG) with agricultural soils representing its largest anthropogenic source. However, the mechanisms involved in N2O emission and factors affecting fluxes response to various nitrogenous fertilizer applications remain uncertain. We conducted four-year (2012–2015) field experiment assess how fertilization scheme impacts emissions from rice-wheat cropping system eastern China. The treatments included Control (CK), Conventional (CF), CF shallow-irrigation (CF+SI), deep-irrigation (CF+DI), Optimized (OF), OF Urease inhibitor (OF+UI), conservation tillage (OF+CT) Slow-release (SRF). were measured by closed static chamber method. ranged 0.61 μg m-2 h-1 1707 h-1, indicating significant impact of nitrogen type on emissions. highest crop yields for wheat (3515–3667 kg ha-1) rice (8633–8990 observed under SRF OF+UI reduction 16.94–21.20% 5.55–7.93%, respectively. Our findings suggest that can be effective achieving maximum yield lowering
