Product Overview
DMPP (3,4-Dimethylpyrazole Phosphate) is a highly efficient nitrification inhibitor widely used in agriculture to improve nitrogen use efficiency and reduce nitrogen losses from the soil. With its ability to delay the conversion of ammonium to nitrate, DMPP helps retain nitrogen in a more stable form, making it available to crops for a longer period.
Jiangsu Khonor Chemicals Co., Limited offers high-purity DMPP with reliable quality, consistent supply, and global export support.

Production Method
DMPP is synthesized through the controlled cyclization of acetylacetone with dimethylamine and ammonia, followed by phosphorylation using phosphoric acid or phosphorylating agents. This process ensures high purity and stability of the final product.
Raw Materials
Acetylacetone
Dimethylamine
Ammonia
Phosphoric acid or phosphoric anhydride
Mechanism of Action
DMPP slows the activity of Nitrosomonas bacteria in the soil, which are responsible for oxidizing ammonium (NH₄⁺) into nitrate (NO₃⁻). By inhibiting this conversion, nitrogen remains in the ammonium form longer, reducing leaching and denitrification losses.
Applications
Agriculture:
Used with nitrogen fertilizers such as urea, ammonium sulfate, or ammonium nitrate to improve nitrogen efficiency.Fertilizer Industry:
Added to NPK, UAN, or CRF formulations to enhance performance and sustainability.Soil Management:
Improves nitrogen retention, reduces greenhouse gas emissions (e.g., N₂O), and supports long-term soil fertility.
Benefits
Increases nitrogen use efficiency by 20–40%
Reduces nitrogen loss by leaching and denitrification
Enhances crop yield and root development
Environmentally friendly – reduces nitrate contamination and N₂O emissions
Compatible with most nitrogen fertilizers
Effective at low application rates (0.5–1.5 kg/ha)
Global Use by Trusted Brands
DMPP is widely adopted in Europe, China, North America, and South America. It is integrated into branded fertilizers by top agricultural companies for use in cereal crops, vegetables, fruits, and turf management.
