Effect of Chloride Salts on Ammonium Nitrogen Release in Two Hawaiian Soils1

摘要: Akaka silty clay and Wahiawa were treated with the chloride salts of mono-, di-, trivalent cations. Carbon dioxide production in salt-treated samples was slightly less than control. NH₄-N release a direct function salt concentration length incubation. Once NH₄³ ions formed from soil organic-inorganic complexes, different cations had second larger effect on exchange reaction which transferred NH₄ surface sites to solution. The equilibrium state largely dependent nature solution, as well A consideration overall two soils led series, Al > Fe Ca Mg K Na, order decreasing replacing power.
