DuraTec

A range of partly coated slow and controlled release granular fertilizers (with both coated and non-coated NPK granules, mostly with a diameter of 2-4mm), with nitrification inhibitor DMPP (3,4-dimethylpyrazolphosphate) to provide instant and longer-term nutrient release. These are produced by Compo Expert.

The 2N-technology (nitrification inhibitor + coating) aims to improve the efficiency of nutrient release.
