The impact of nitrogen fertilizer (N) application timing on nitrous oxide (N2O) emissions is inconsistent in the literature. This inconsistency is attributed to year-to-year weather variations, which affect soil conditions around N application time. Planting dates (PD) also vary year-to-year based on weather, and PD can influence N timing decisions.

结合测量和建模，揭示氮肥施用时间对玉米 N2O 排放的长期影响


氮肥 （N） 施用时间对一氧化二氮 （N2O） 排放的影响在文献中不一致。这种不一致归因于每年的天气变化，这会影响施氮前后的土壤条件。种植日期 （PD） 也每年根据天气而变化，PD 会影响 N 时间决策。
