Product Introduction

DMPP (3,4-Dimethylpyrazole Phosphate) is a highly effective nitrification inhibitor designed to slow down the conversion of ammonium nitrogen (NH₄⁺) into nitrate nitrogen (NO₃⁻) in soil. By reducing nitrogen leaching and nitrous oxide emissions, DMPP helps farmers achieve better nitrogen utilization, increased yields, and more sustainable farming practices.

Specifications:

Production Method
DMPP is synthesized through a controlled reaction of 3,4-dimethylpyrazole with phosphoric acid under optimized conditions to ensure high purity and stability. Jiangsu Khonor Chemicals Co., Limited applies strict quality control in every production stage to meet international agricultural standards.

Raw Materials

• 3,4-Dimethylpyrazole

• Phosphoric acid (H₃PO₄)

• Purified water

Mechanism of Action
DMPP inhibits the activity of Nitrosomonas bacteria in the soil, delaying the oxidation of ammonium nitrogen to nitrate nitrogen. This process helps retain nitrogen in a form available to plants for longer periods, improving fertilizer efficiency and reducing environmental nitrogen losses.

Application Fields

• Blended with nitrogen-based fertilizers (e.g., urea, ammonium sulfate, UAN solution)

• Applied in cereal crops, corn, rice, vegetables, and grassland

• Suitable for slow-release and controlled-release fertilizers

• Used in both dryland and irrigated farming systems

Company Advantages

• Over 10 years of experience in chemical exports

• Consistent product quality with strict QC standards

• Flexible packaging and OEM services

• Global logistics support for bulk shipments

Ordering Information

• Minimum Order Quantity (MOQ): 25 kg

• Lead Time: 7–15 days depending on order quantity

• Shipping: Available worldwide by sea, air, or courier
