What is the important of ammonia in our life?

• Ammonia is important because it is a vital source of nitrogen to support plant life. It is also used industrially to make dyes, plastic, explosives, drugs, nitric acid and ammonium hydroxide.  
• Diluted ammonium hydroxide is used as a household cleaner. 
• Plants use the nitrogen in ammonia to produce necessary proteins.  
• Urea, ammonium sulfate, ammonium nitrate, ammonium phosphate and pure ammonia are all used as commercial fertilizers for nitrogen-poor soil. Ammonium nitrate is also a component of explosives, ammonium phosphate is used in flame-retardant wood treatments and ammonium sulfate is present in chemicals used to tan leather. 
• Ammonium salts are used in dry-cell batteries, smelling salts and water treatments.  
• Liquid ammonia is used as an industrial refrigerant. Ammonia makes an ideal refrigerant because it can absorb large amounts of heat without its temperature rising.
