Incorporating high organic carbon amendments (HCA) in the soil can promote microbial nitrogen (N) immobilization. HCA incorporation is thought to reduce N loss via nitrate (NO₃⁻); however, it often increases nitrous oxide (N₂O) emissions in upland soils.

C:N:P化学计量对土壤一氧化二氮排放和氮保留的影响

在土壤中加入高有机碳改良剂 (HCA) 可以促进微生物氮 (N) 的固定化。HCA 被认为通过硝酸盐 (NO ₃ ^- )减少 N 损失；然而，它通常会增加高地土壤中一氧化二氮 (N ₂ O) 的排放。
