Reducing How Much Nitrogen Enters a Lake Has Little Impact on Algal Blooms, Find Canadian Scientists

Press release from IISD 

WINNIPEG, December 18, 2017—Lakes suffering from harmful algal blooms may not respond to reduced, or even discontinued, artificial nitrogen loading. Many blue-green algae responsible for algal blooms can fix atmospheric nitrogen dissolved in the water, and therefore water stewards should focus their efforts on removing phosphorus from lakes to combat algal blooms.

Information can be found in a recently published article in Springer’s Ecosystems journal, Biological Nitrogen Fixation Prevents the Response of a Eutrophic Lake to Reduced Loading of Nitrogen: Evidence from a 46-Year Whole-Lake Experiment. The paper presents the results of a 46-year whole-ecosystem experiment at IISD Experimental Lakes Area in Northwestern Ontario, Canada.
