About Ammonia nitrogen

Ammonia nitrogen means nitrogen present in the form of free ammonia(NH3)and ammonium ions(NH4)in water. The nitrogen content of animal organic compounds is generally higher than that of vegetable organic compounds. At the same time, nitrogen-containing organic matter in human and animal feces is very unstable and easily decomposed into ammonia. Therefore, when the content of ammonia nitrogen in water increases, it refers to the nitride in the form of ammonia or ammonium ions.
