Reducing Phosphorous In Lakes May Weaken Their Ability To Remove Nitrogen

Phosphorus is found in Minnesota’s many lakes after it is washed into them, frequently in the form of agricultural and lawn fertilizers. Excessive amounts of the nutrient can then cause algae blooms and otherwise lower the quality of the water, an issue that many water-cleanup efforts attempt to correct by reducing the phosphorous levels in affected lakes. The University of Minnesota researchers note this focus on cutting levels of phosphorous can result in significant accumulations of nitrogen in the lakes and increased nitrogen pollution in rivers and coastal regions downstream from them.

“Freshwater ecosystems, including lakes, streams and wetlands, are a large global sink for reactive nitrogen,” lead author Jacques C. Finlay, an associate professor in the College of Biological Sciences, said in a statement. “By reducing one aquatic pollutant -- phosphorus -- we are in some cases re...
