Diammonium phosphate CAS7783-28-0, also known as diammonium hydrogen 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. It is suitable for various crops and soils, especially for crops that prefer nitrogen and phosphorus. It can be used as a base fertilizer or topdressing, and should be applied deeply. Diammonium phosphate refers to the standard product containing N18% and P2O548%, with a crystal shape of flat and inclined prism. The solubility in water at 25 ℃ is 71%, and the pH of its saturated solution reaches 8, which is much higher than that of monoammonium phosphate. Due to the alkaline nature of the saturated solution of diammonium phosphate, its application in acidic soil can reduce the fixation of phosphorus by iron and aluminum, maintaining a high availability of phosphorus. Therefore, the use of diammonium phosphate in acidic soil is advocated.
