Effect of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on N-turnover, the N₂O reductase-gene nosZ and N₂O:N₂ partitioning from agricultural soils.

ABSTRACT: Nitrification inhibitors (NIs) have been shown to reduce emissions of the greenhouse gas nitrous oxide (N₂O) from agricultural soils. However, their N₂O reduction efficacy varies widely across different agro-ecosystems, and underlying mechanisms remain poorly understood. To investigate effects of the NI 3,4-dimethylpyrazole-phosphate (DMPP) on N-turnover from a pasture and a horticultural soil, we combined the quantification of N₂ and N₂O emissions with ¹⁵N tracing analysis and the quantification of the N₂O-reductase gene (nosZ) in a soil microcosm study. Nitrogen fertilization suppressed nosZ abundance in both soils, showing that high nitrate availability and the preferential reduction of nitrate over N₂O is resp
