Technical Document

Brief Overview

Diammonium phosphate is a water-soluble ammonium salt that is one of the most widely used phosphorus fertilizers because of its relatively high nutrient content.

Manufacturing Process

Phosphoric acid and ammonia are reacted under controlled conditions to produce diammonium phosphate. The heated slurry is subsequently cooled, granulated, and sieved. It works well with low pH soil because it includes two ammonia molecules, one of which will turn back into ammonia in an alkaline environment.

Agricultural Industry

Diammonium phosphate (DAP) is valued for its high nutrient content. It provides a readily available source of nitrogen (N) and phosphorus (P) to plants, two essential nutrients crucial for their growth and development. The nitrogen in DAP is in the ammonium form, which is gradually converted to nitrate by soil bacteria, making it available to plants over time.

Diammonium phosphate is often a component of blended fertilizers due to its balanced nitrogen-phosphorus content. It can be combined with other fertilizers to meet specific nutrient requirements for different crops and soil conditions.

Food Industry

Diammonium phosphate is used as a buffer, yeast food, dough regulator, leavening agent, and brewing fermentation additive.

Other Applications

Diammonium phosphate serves as a buffer and analytical reagent. In addition, it is utilized for electronic tubes, printing plates, medication, and fire safety.
