Why are ammonia results reported as NH3-N or Ammonia-N? Thanks

NH3,NO2/NO3,TKN are all reported as N so that they can uniformly compared for relative N quantification

It is ultimately to ensure that you are comparing apples to apples, or should I say, atoms to atoms.  17 grams of ammonia, NH3 and 101 grams of KNO3 both contain 14 grams of Nitrogen.  Also remember that a part per million in this case is milligrams of Stuff per liter volume of solution.
