Adding carbon or nitrogen to a river did not affect algae, but adding phosphorus caused heavy algal growth. Controlling phosphorus is crucial for fixing eutrophication in rivers and lakes. Phosphorus sticks to sediment particles more than it precipitates. The rate of phosphorus sticking and unsticking affects the water's chemistry and biology. The type and amount of phosphorus in lake sediments depend on the sediment's composition. Not much is known about how sediment characteristics affect phosphorus uptake and release. This study looked at how inorganic phosphorus sticks to different sizes of sediment particles in Blackstrap Lake. The researchers used a simple system to quickly evaluate their results.
