The efficacy of 3,4-dimethylpyrazole phosphate on N2O emissions is linked to niche differentiation of ammonia oxidizing archaea and bacteria across four arable soils

The nitrification inhibitor, 3,4-dimethylpyrazole phosphate (DMPP), can be used to reduce N2O emissions from agricultural ecosystems. However, the effectiveness of DMPP varies among soils, and this is due to both abiotic (e.g. soil properties) and biotic factors (e.g. ammonia oxidizers and denitrifier communities). Understanding the nature of these effects is necessary to improve the efficacy of DMPP, therefore encouraging wider adoption and...
