Soil Type Controls the Effects of the Nitrification Inhibitor DMPP on Nitrate Leaching and Mineral N Retention Under Simulated Heavy Rainfall

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Nitrate (NO3−) leaching is a major nitrogen (N) loss pathway in agriculture and may increase with more frequent heavy rainfall. Nitrification inhibitors, such as 3,4‐dimethylpyrazole phosphate (DMPP), can reduce these losses, but their effectiveness under frequent heavy rainfall events remains unclear, which limits their targeted ...
