The key difference between ammonia and ammoniacal nitrogen is that the ammonia is an inorganic compound having the chemical formula NH3 whereas the ammoniacal nitrogen is a measure of the amount of ammonia in a sample.. Ammonia is a gaseous compound with a characteristic, pungent odor. Although it is useful on many occasions, it is a toxic compound as well.

Ammoniacal Nitrogen. Ammoniacal nitrogen is nitrogen derived from ammonia and is one form of nitrogen that plants can readily use. Ammoniacal nitrogen is most commonly found in the soil as ammonium, which is created naturally by the nitrogen cycle or introduced through synthesized fertilizers and deposited into the soil for plant use.

Ammoniacal nitrogen (NH 3-N) Ammoniacal nitrogen (NH 3-N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ammonia, and returned to ammonia via organic processes, in water or waste liquids. It is a measure used mainly for quantifying values in waste treatment and water purification systems, as well as ...

TAN (total ammonia nitrogen) is the total amount of nitrogen in the forms of NH3 and NH4+ in water. In aquaculture, TAN concentration must be less than 0.5 mg/L. There are two processes where micro-organisms consume TAN in water: 1. The assimilation process: The heterotrophic bacteria assimilate TAN into microbial protein.

ammoniacal nitrogen when growing conditions are cool and wet. When cold gray weather occurs a common strategy used by growers is to alternate to a 15-0-15 “Dark Weather Forumla.” This eliminates the extra ammonium input temporarily, but then allows growers to return to their normal formula when growing conditions improve. ...
