1,2,3-Triazoles as Nitrification Inhibitors for Australian Soils

Nitrification is the multi-step oxidation of ammonium (NH4 +) to nitrate (NO3-). Nitrification inhibitors (NIs) can be used to reduce nitrogen losses from synthetic fertilisation application, by slowing the microbial conversion of nitrogen out of the more stable NH4+ form.

Commercial NIs including 3,4-dimethyl pyrazolephosphate (DMPP) provide variable results under Australian field conditions.1 1,2,3-Triazoles were investigated as a new class of NIs that are synthetically accessible in few steps, and may provide more consistent efficacy in Australian soils, under varied climatic and edaphic conditions
