Highlights • N2O EFs from urine deposition to grassland are larger if applied in spring.• Meta-analysis showed a significant effect of season and not of treatment on the N2O EFs.• Methane emissions were larger from the dung application compared to urine.• CH4 totals were significantly different across seasons (lowest in spring).• CH4 totals were not significantly different between treatments.

使用含或不含硝化抑制剂 DCD 的牛尿和粪便对英国草原土壤温室气体排放的影响

亮点 • 如果在春季应用，从尿液沉积到草地的 N2O EFs 更大。• 荟萃分析显示季节而非处理对 N2O EFs 的显着影响。• 与尿液相比，粪便应用产生的甲烷排放量更大。• CH4不同季节的总量显着不同（春季最低）。 • CH4 总量在处理之间没有显着差异。
