Raw Materials

Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:

Nitrogen	Phosphorus	Potassium
Calcium nitrate	urea	Single superphosphate	Kainit
Ammonium bicarbonate	Ammonium chloride	Rock phosphate	Potassium chloride
Nitrate of soda	Ammonium sulphate nitrate	Dicalcium phosphate	Potassium sulphate
Ammonium sulphate	Ammonium nitrate	Triple superphosphate	Potassium nitrate
