Effects of animal manure and nitrification inhibitor on N₂O emissions and soil carbon stocks of a maize cropping system in Northeast China.

ABSTRACT: The incorporation of animal manure (AM) in soil plays an essential role in soil carbon sequestration but might induce higher soil nitrous oxide (N₂O) emissions. The use of nitrification inhibitors (NI) is an effective strategy to abate N₂O emission in agro-ecosystems. However, very few studies have evaluated the effectiveness of applying NI under the combined application of organic and inorganic fertilizers for increasing soil carbon sequestration and reducing N₂O emissions simultaneously in Northeast China. Here, a four-year field experiment was conducted with three treatments [inorganic fertilizer (NPK), inorganic fertilizer + manure (NPKM), and inorganic fertilizer with NI + manure (NPKI + M)], in a rainfed maize cropping system in Northeast China.
