| Common Name | Nh4(+) | ||||||||

| Description | Ammonium is an important source of nitrogen for many plant species, especially those growing on hypoxic soils. However, it is also toxic to most crop species and is rarely applied as a sole nitrogen source. The ammonium (more obscurely: aminium) cation is a positively charged polyatomic cation with the chemical formula NH4+. It is formed by the protonation of ammonia (NH3). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations (NR4+), where one or more hydrogen atoms are replaced by organic radical groups (indicated by R). Ammonium is found to be associated with N-acetylglutamate synthetase deficiency, which is an inborn error of metabolism. | ||||||||
