Nitrogen saturation of watersheds contributes to environmental problems such as reduced drinking water quality, nitrateinduced toxic effects on freshwater organisms, increased soil acidification and aluminum mobility, increased emissions from soil of nitrogenous greenhouse trace gases, reduction of methane consumption in soil, and forest decline and reduced productivity.
Nitrogen has a point of saturation that affects the environment differently.
Nitrogen cannot be saturated through natural or man made forces.
