Diammonium Phosphate DAP

Diammonium phosphate

Our DAP is a fully water-soluble fertilizer, a highly efficient source of phosphorus and nitrogen for plants.DAP diammonium phosphate is recommended for use at the beginning of the growth season, when phosphorus availability is crucial for the establishment of root system. Ammonium phosphate dibasic can be tank-mixed with other fertilizers* to meet crop nutritional needs throughout the growth cycle.

The advantages of Diammonium Phosphate:

Fully water-soluble
Consists of 100% plant nutrients
Free of chloride, sodium and other detrimental elements for plants
Suitable for the production of nutrient solutions

Diamminium Phosphate Properties:
Colorless transparent monoclinic crystal or white powder, easy soluble in water, gradually lose ammonia to become into ammonium dihydrogen phosphate when exposed into the air, its aqueous solution is alkali.

Ammonium phosphate dibasic Uses:

Dammonium phosphate is used as a fertilizer. Diammonium phosphate is the most widely used phosphate fertilizer. It has an analysis of 18-46-0. For most soils with pH less than 7.5, the agronomic effects of diammonium and monoammonium phosphates are equal.

Ammonium phosphate dibasic is manufactured by reacting phosphoric acid and ammonia.DAP diammonium phosphate contains two ammonia molecules. In alkaline soil conditions, one of the ammonia molecules in Diammonium phosphate will revert to ammonia. Diammonium hydrogen phosphate is alkaline with a high pH, exceeding 7.5. Ammonium phosphate dibasic is excellent for low pH or alkaline soils.
