What is Diammonium Phosphate DAP?
Diammonium Phosphate DAP is colorless and odorless crystal or white crystalline powder. Melting point: 190. One gram of this product is dissolved in 1.7 mL of water, 0.5 mL of boiling water, insoluble in ethanol and acetone. The ph of the solution is about 8. Diammonium Phosphate DAP is a compound fertilizer containing both nitrogen and phosphorus nutrients. Diammonium hydrogen phosphate is a high concentration quick acting fertilizer that is easily soluble in water and has less solid matter after dissolution. Diammonium Phosphate DAP is suitable for various crops and soils, especially for crops that prefer nitrogen and phosphorus.
