Ammonium Dihydrogen Phosphate

Short Description:

Ammonium Dihydrogen Phosphate, also known as monoammonium phosphate, white crystal.

Chemical formula is NH₄H₂PO₄

Formula weight is 115.03

CAS No. 7722-76-1

As a fertilizer, it is most suitable to apply ammonium phosphate during crop growth. Ammonium phosphate is acidic in the soil, and it may have adverse effects if it is too close to the seed. In acid soil, it is better than ordinary calcium and ammonium sulfate, and in alkaline soil. It is superior to other fertilizers; it should not be mixed with alkaline fertilizers to avoid reducing fertilizer efficiency. For example, when lime is used in the southern acidic soil, monoammonium phosphate should be applied after a few days.
