ARM UAN™

ARM UAN™ keeps your UAN working longer with proven volatilization and nitrification control.

Description

ARM UAN is a dual-action nitrogen stabilizer engineered for UAN. It protects against both above-ground and below-ground nitrogen losses by slowing urea hydrolysis and inhibiting microbial conversion of ammonium to nitrate. With ARM UAN, more of your applied nitrogen stays available in the root zone—where your crop needs it most.

When to Use

Apply directly to UAN at blending or just prior to application.

Application Rate

ALWAYS READ LABEL BEFORE USE.

Blend 1–2 L ARM UAN™ per 1000 kg UAN or 1.2–2.4 L per 1000 kg urea.

How it Works

Active Ingredients:
N-(n-butyl) thiophosphoric triamide (NBPT): 18%
3,4-dimethylpyrazole phosphate (DMPP): 3%

These two proven technologies work in tandem to delay nitrogen transformations, reduce environmental loss pathways, and extend availability for crop uptake.

Benefits

Dual-action nitrogen stabilizer

A liquid fertilizer additive that controls ammonia volatilization and loss of nitrogen through nitrification from urea and urea ammonium nitrate (UAN) fertilizers.

ACTIVE INGREDIENTS: 18% NBPT (N-(n-butyl) thiophosphoric triamide); 3% DMPP (3,4-dimethylpyrazole phosphate).
INACTIVE INGREDIENTS: (79%): [NMP (N-methyl-2-pyrrolidone), propylene glycol, emulsifier, preservative, dye].
BLENDING INSTRUCTIONS: READ THE ENTIRE LABEL BEFORE USING THIS PRODUCT.
Blending into UAN: Use 1 – 2 L of ARM UAN™ / 1000 kg UAN solution. Fill spray tank with half the desired amount of UAN, Measure the recommended quantity of ARM UAN™ and add to the tank. Mix well. Add other products at this stage, if needed. Add the second half of the UAN solution. Continue mixing until well blended. Keep agitator running while mixing. Blending into Urea: Use 1.2 – 2.4 L ARM UAN™ / 1000 kg Urea. For uniform blending, use a blender with impregnation equipment. Weigh the urea and transfer to blender. Add the required amount of ARM UAN™ to the urea in the blender. Blend until the ARM UAN™ is uniformly mixed into the urea. Do not add any other fertilizer materials until ARM UAN™ is thoroughly distributed. If mixture appears wet or sticky, a drying agent may be added at this time. NOTE: Density = 9.2 lb per gallon (1.1 grams / cubic centimeter) at 20°C (68°F).
