Abstract Woody peat was used as an additive to compost with pig manure in 1.2 m3 composting reactors under aerobic conditions for a 77 days period to estimate the effect on the compost maturity and gaseous emissions (NH3, N2O, and CH4). Pig manure was also composted with cornstalks (the traditional method) as a control treatment. The results showed that both cornstalks and woody peat composts reached the required maturity standard. Composting with woody peat as a bulking agent was found to reduced NH3 emissions by 36% than the cornstalks amended treatment. Although CH4 emission increased by adding woody peat, N2O emission was considerably reduced, resulting in a slight decrease in total greenhouse gas emissions. More importantly, woody peat could reduce the losses of total carbon and total nitrogen, improve the compost quality as fertilizer.

木本泥炭作为添加剂对猪粪堆肥过程中成熟度和气体排放的影响

摘要 木本泥炭作为添加剂在 1.2 m3 堆肥反应器中有氧条件下与猪粪一起堆肥 77 天，以估计对堆肥成熟度和气体排放（NH3、N2O 和 CH4）的影响。猪粪也用玉米杆（传统方法）堆肥作为对照处理。结果表明，玉米秸秆和木本泥炭堆肥均达到了要求的成熟度标准。发现使用木本泥炭作为填充剂的堆肥比玉米秸秆改良处理减少了 36% 的 NH3 排放。尽管添加木本泥炭增加了 CH4 排放，但 N2O 排放显着减少，导致温室气体排放总量略有下降。更重要的是，木本泥炭可以减少总碳和总氮的损失，提高作为肥料的堆肥质量。
