molecular formula: (NH4)3PO4
CAS: 10124-31-9
Appearance:
colorless crystal or white powder
Properties:
Ammonium phosphate for inorganic compounds, pointing to commonly (NH4) 2HPO4 ･ NH4H2PO4, colorless crystalline off-white powder, sometimes for particle, soluble in water. Contain nitrogen, phosphorus, is a kind of compound fertilizer.
Use:
Ammonium phosphateis mixed fertilizer production of a kind of ideal basis for fertilizers. Ammonium phosphate of nitrogen to ammoium nitrogen, phosphorus are almost water soluble state, suitable for all kinds of crops and soil in application, should deep give. Appropriate as basal application and seeds. Because the phosphorus content for Ammonium phosphate nitrogen of 3 ~ 4 times, so besides leguminous crops outside, fertilization of the match was a certain amount must be pure nitrogen
