ARM U™ 28% NBPT

A liquid fertiliser additive that controls ammonia volatilisation from urea and urea ammonium nitrate (UAN) fertilisers.

Category: Nitrogen Stabilisers

Description

ARM U™ 28% NBPT is an NBPT based fertiliser additive that allows plants to absorb and utilise nitrogen efficiently, which otherwise disappears too quickly through conversion to ammonia gas.

When to Use

Whenever urea or UAN fertiliser is applied to soil.

Benefits

Best for High Nitrogen Loss Situations
Effective in high pH soils and low moisture conditions.

Inhibits NH3 Loss
Reduces ammonia volatilisation by up to 92% compared to untreated urea.

Maximises Fertiliser Efficiency
Minimises nitrogen loss, boosts fertiliser efficiency, and reduces costs.

Effortless Application
The liquid formulation allows for easy application with thorough coverage and minimal handling issues.

Consistent Performance
Reliable performance across a wider range of environmental conditions.

Add DMPP for Dual Protection
Can be mixed with ARM U™ 16% DMPP to inhibit all forms of nitrogen loss.

How it Works

Nitrogen is essential for plant life and growth and is therefore a component of many fertilisers. However, up to 50% of the nitrogen applied as soil fertiliser is unavailable to plants because it is quickly converted to ammonia gas and released into the atmosphere. ARM U 28% NBPT inhibits this enzymatic process, allowing nitrogen to be absorbed through the plant roots.

Unlike other NBPT formulations, ARM U 28% NBPT is patented and an improved formulation that contains polymers (spreader molecules) that increase NBPT’s binding rates to urease enzyme leading to improved NBPT activity. This increased activity enables a lower active ingredient and a lower use rate. In addition, ARM U 28% NBPT is formulated to have a high buffering capacity to keep the solution pH below 7 and to protect and fully utilise the nitrogen present in the NBPT molecule.

UREASE INHIBITOR

A liquid fertiliser additive that controls ammonia volatilisation from urea and urea ammonium nitrate (UAN) fertilisers.

ACTIVE INGREDIENT: 28.3% N-(n-butyl) thiophosphoric triamide (NBPT).
INACTIVE INGREDIENTS: (71.7%) [N-methyl-2-pyrrolidone (NMP), propylene glycol, emulsifier, preservative, dye] READ THE ENTIRE LABEL BEFORE USING THIS PRODUCT.
BLENDING INSTRUCTIONS:
Blending into UREA: Use 2 L ARM U™/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 U™ 28% NBPT to the urea in the blender. Blend until the ARM U™ 28% NBPT is uniformly mixed into the urea. Do not add any other fertiliser materials until ARM U™ 28% NBPT is thoroughly distributed. If mixture appears wet or sticky, a drying agent may be added at this time.
Blending into UREA-AMMONIUM NITRATE (UAN) SOLUTIONS: Use 1.2 L ARM U™ 28% NBPT / 1000 kg UAN solution. Fill spray tank with half the desired amount of UAN, Measure the recommended quantity of ARM U™ 28% NBPT 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.
NOTE: Density=1.1 grams / cubic centimeter at 20°C.

SECTION 16 – OTHER INFORMATION
ADDITIONAL INFORMATION	WORK PRACTICES – SOLVENTS: Organic solvents may present both a health and flammability hazard. It is recommended that engineering controls should be adopted to reduce exposure where practicable (for example, if using indoors, ensure explosion-proof extraction ventilation is available). Flammable or combustible liquids with explosive limits have the potential for ignition from static discharge. Refer to AS 1020 (The control of undesirable static electricity) and AS 1940 (The storage and handling of flammable and combustible liquids) for control procedures. RESPIRATORS: In general, the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn, ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air-powered or air-supplied respirators should be considered where prolonged or repeated use is necessary. PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as form of product, method of application, working environment, quantity used, product concentration, and the availability of engineering controls should be considered before final selection of personal protective equipment is made. HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: form of product; frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used; and method of application. Given that it is impractical to prepare a report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.
