| 英文摘要 | Nitrifier denitrification (ND) is recognized as an important pathway for N2O production in agricultural soils, yet its contributions under different moisture contents are poorly quantified. Using an enriched dual isotope (N-15 - O-18) approach, we estimated N2O production from ND across eight moisture levels (40-120% water-filled pore space, WFPS) in a typical agricultural soil from the North China Plain. Total N2O flux began to increase when WFPS exceeded 70%, peaking at 100% WFPS, indicating substantial N2O emission potential in wet soils. In contrast, the N2O production from ND increased gradually from 40-70% WFPS, rose sharply from 70-90% WFPS, stabilized between 90-100% WFPS, and declined rapidly from 100-120% WFPS. ND contributed approximately 20%, 80%, and 30% of N2O emissions under low (40-50% WFPS), intermediate (60-70% WFPS), and high (80-120% WFPS) moisture conditions, respectively. Future contributions from ND may increase as irrigation and extreme rainfall events become more frequent under changing climates. |
