BEST® Fertilizer: Spread the Word™!

UMAXX® is a uniquely formulated combination of N-(n-butyl) thiophosphoric triamide, (NBPT): a urease inhibitor and dicyandiamide; a nitrification inhibitor. NBPT stops volatilization for up to two weeks, thus minimizing nitrogen loss and reducing the potential for turf burn. Dicyandiamide blocks the microbial conversion of ammonium nitrogen to nitrate nitrogen. This keeps the nitrogen in the stable ammonium form and in the soil for more efficient plant utilization. It also greatly reduces the leaching of nitrates that can contaminate groundwater. UMAXX® is available in a standard size particle and a mini particle. It is used as a nitrogen component in blended fertilizers and as a soluble nitrogen source for use in liquid applications. UMAXX® is ideal for use on golf courses or wherever quality turf is desired.
