Applications & Use Cases
- ▸ Active nitrification inhibitor blended into stabilized ammonium and urea-ammonium nitrogen fertilizers to slow microbial oxidation of ammonium to nitrate, extending nitrogen availability to crops.
- ▸ Reduces nitrate leaching into groundwater and gaseous nitrous-oxide emissions from agricultural soils, supporting nutrient-use-efficiency and environmental-compliance fertilizer programs.
- ▸ Dosed at low parts-per-thousand loadings (typically ~1% of fertilizer ammonium-N) into granular, liquid, and suspension fertilizer formulations during manufacturing.
- ▸ Formulated into enhanced-efficiency fertilizer (EEF) products for cereals, row crops, vegetables, and turf where a single nitrogen application must remain plant-available over a longer window.
- ▸ Supplied to fertilizer blenders and agrochemical formulators as a technical-grade additive sourced to specification for incorporation into branded stabilized-nitrogen product lines.
