    Calcium cyanamide is an important nitrogen fertilizer. The nitrogen cannot be absorbed by plants directly, but can only be absorbed by plants through the conversion of water and carbon dioxide. It is used as a base fertilizer and suitable for acid soil. Reacting with water to produce ammonia and calcium carbonate is a method of producing synthetic ammonia. It can also be used as a defoliant or herbicide. In the chemical industry, it is the raw material of cyanamide, dicyandiamide, melamine, which can be further processed into thiourea and guanidine. In the iron and steel industry, it is used as nitriding agent and cast iron desulfurizer for carbon steel and low alloy. In waste treatments, it can be used to remove formaldehyde in wastewater.
