Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem
Acid precipitation has been shown to reduce phosphorus (P) outputs from terrestrial sources. We present field evidence that the in-lake P cycle may...
