ISO9001 Di Ammonium Phosphate 98.0% Diammonium Phosphate DAP Fertilizer
PH Value 7.8-8.2 Di-Ammonium Phosphate 98.0% Main Content for Enhanced Plant Nutrition
Product Description:
Diammonium hydrogen phosphate, also known as diammonium phosphate and commonly abbreviated as DAP, is found in the form of colorless transparent monoclinic crystals or a white powder. The substance has a relative density of 1.619 and a melting point of 190℃.
It is easily soluble in water, and its aqueous solution is alkaline. A 1% aqueous solution of DAP has a pH of 8.0, while a 0.1 mol/L solution has a pH of 7.8. On the other hand, it is not soluble in alcohol and dimethyl ketone.
Over time, when DAP is exposed to air, it gradually loses about 8% of its ammonia content and transforms into ammonium dihydrogen phosphate. It also can undergo a reaction with ammonia water to produce triammonium phosphate.
Features:
High-Efficiency Nitrogen-Phosphorus Compound Fertilizer is composed of 21% nitrogen and 53% phosphorus content, offering plants water-soluble phosphorus and ammonium nitrogen benefits.
This fertilizer boasts a high purity level of over 98% , making it fully soluble in water and quickly absorbable by plants.
It is free of harmful substances to plants, making it ideal for foliar spraying and drip irrigation applications.
With a pH value ranging between 7.8 and 8.2 , this fertilizer effectively helps in regulating the pH balance of both the soil and the physiological cells of the plants.

Applications:
In industry, industrial-grade diammonium hydrogen phosphate (DAP) is used as a fire retardant for textiles, wood, and paper, and also serves as an additive in fire-resistant coatings.
In agriculture, it functions as a high-efficiency, chlorine-free nitrogen-phosphorus compound fertilizer. It dissolves rapidly in water, which facilitates crop absorption. Its weakly alkaline nature helps effectively ameliorate acidic soils.
It is widely used in all kinds of fruits, vegetables, fruit trees, and cash crops, with remarkable economic benefits. It is applicable to all kinds of soil.
- Base fertilizer application: 10-20kg/mu.
