Lime nitrogen is mainly used in the production of carbendazim, benomyl and intermediate monocyandiamide. When used as fertilizer, because calcium cyanamide has strong alkalinity, it is suitable for acidic soil and is generally used as base fertilizer. When exposed to water, cyanamide is initially formed, which is toxic to plants, but it is quickly transformed into ammonia. This toxic effect makes plant leaves fall off, so it can also be used as herbicide, fungicide, insecticide and cotton defoliant. Calcium cyanamide can also be used as raw materials for the production of plastics and explosives. It can also be used for steel nitriding, gold and silver ore treatment, removal of nitrogen oxide in waste gas, removal of formaldehyde in waste water and corrosion inhibitor of brine.
