Inorganic Forms of Nitrogen

Inorganic forms of nitrogen stored in wetlands include ammonium, nitrate, and nitrite. They can be found in soil pore water. Ammonium may be present on the soil cation exchange complex or permanently trapped within the clay layer. Inorganic N forms are not typically very stable, comprising 1% of the total N within wetlands.
