The effect of the nitrification inhibitor 3,4-dimethylpyrazole phosphate on soil mineral nitrogen processes

Nitrification is the biological oxidation of ammonium to nitrate. The production of nitrate means that nitrogen can be lost from the soil system via nitrate leaching or denitrification. To mitigate these losses, nitrification inhibitors like 3,4-dimethylpyrazole phosphate (DMPP) can be used to suppress the oxidation of ammonium.

Australian soils are highly weathered and often have acidic topsoil’s, which may alter the effectiveness of inhibitors. The project focuses on the effect of DMPP on soil mineral nitrogen processes in Australian soils and if varying soil properties alter the behavior of DMPP.
