Applications & Use Cases
- ▸ Added to granular and liquid urea fertilizers as a urease inhibitor that slows enzymatic hydrolysis of urea, cutting ammonia volatilization losses and improving nitrogen-use efficiency.
- ▸ Formulated into enhanced-efficiency nitrogen (EEN) fertilizer treatments, typically blended with solvents and stabilizers and coated onto urea prills at low part-per-thousand loadings.
- ▸ Combined with the nitrification inhibitor DCD in dual-inhibitor agronomic blends to protect both the ammonium and nitrate pathways of applied nitrogen.
- ▸ Used in UAN (urea-ammonium nitrate) liquid solutions and fertigation programs to extend the window before surface-applied urea must be incorporated by rain or irrigation.
- ▸ Supplied as a technical active ingredient to agrochemical formulators producing branded urease-inhibitor adjuvants for broadacre row crops, pasture, and turf.
