ARM U™ 16% DMPP

A liquid additive for urea and UAN fertilisers that reduces nitrogen loss by inhibiting nitrification.

Description

Nitrogen fertiliser applied in certain conditions is prone to losses through nitrification leading to runoff, leaching, and denitrification (N₂O emissions). ARM U™ 16% DMPP slows down the nitrification process, thereby extending the availability of nitrogen in the soil and reducing fertiliser loss. By doing so, it ensures that plants have continuous access to this critical nutrient, fostering healthier growth and maximising yield potential.

When to Use

Whenever urea or UAN fertiliser is applied to soil.

Benefits

Slows Down the N Cycle
Slows the conversion of ammonium to nitrate, enhancing the efficiency of nitrogen fertilisers.

Limits Leaching and Run-off
Reduces nitrogen leaching and runoff by keeping nitrogen in the stable ammonium form longer.

Reduces N₂O Emissions
DMPP inhibits nitrification, reducing nitrous oxide emissions.

Improves Nitrogen-Use Efficiency
Maximises fertiliser efficiency, lowering overall costs by reducing the amount needed.

Add NBPT for Dual Protection
Can be mixed with ARM U™ 28% NBPT to inhibit all forms of nitrogen loss.

Less Product, More Impact
Requires less product per metric tonne of fertiliser compared to competitor brands.

How it Works

ARM U 16% DMPP contains 3,4-Dimethylpyrazole phosphate (DMPP), which inhibits nitrogen oxidation or nitrification by eliminating nitrosomonas and nitrobacter bacterial activity.

While Active AgriScience stands behind the quality of our products, Active AgriScience cannot guarantee the same, or similar, yield results due the effects of variables outside of our control (soil conditions, weather, pests, diseases, tank mix partners, application rates, and errors in mixing and application). We encourage all prospective customers to run trials of our products before broad acreage adoption.

READ THE ENTIRE LABEL BEFORE USING THIS PRODUCT.

ACTIVE INGREDIENTS: 16.1% DMPP (3, 4-dimethylpyrazole phosphate).

INACTIVE INGREDIENTS: (83.9%) NMP (N-methyl-2-pyrrolidone), propylene glycol, emulsifier, preservative, dye.

BLENDING INSTRUCTIONS:

Blending into UREA-AMMONIUM NITRATE (UAN) SOLUTIONS: Use 0.35 L ARM U™ 16% DMPP/ 1000 kg UAN solution. Fill spray tank with half the desired amount of UAN, Measure the recommended quantity of ARM U™ 16% DMPP 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 0.6 L ARM U™ 16% DMPP/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™ 16% DMPP to the urea in the blender. Blend until the ARM U™ 16% DMPP is uniformly mixed into the urea. Do not add any other fertiliser materials until ARM U™ 16% DMPP is thoroughly distributed. If mixture appears wet or sticky, a drying agent may be added at this time. This product can be mixed with ARM U™ 28% NBPT to mitigate the losses from ammonia volatilisation along with nitrification and denitrification.

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.
