NovaTec

A range of granular (plus one liquid N) NPK fertilisers with added nitrification inhibitor DMPP (3,4-dimethylpyrazolphosphate) which helps to reduce leaching. The granules are 2-4mm in diameter, averaging 3.2mm (except where indicated below). The conversion of ammonium to nitrate is delayed during the active phase of DMPP, which is typically 4 to 10 weeks following application (depending on the soil temperature and soil humidity). These are produced by Compo Expert.
