eutrophication Scientific  
/ yo̅o̅-trŏf′ĭ-kāshən /
  1. The process by which a lake, pond, or stream becomes eutrophic, typically as a result of mineral and organic runoff from the surrounding land. The increased growth of plants and algae that accompanies eutrophication depletes the dissolved oxygen content of the water and often causes a die-off of other organisms.

From Los Angeles Times

Nor could an excess supply of nitrogen promote phytoplankton growth -- and therefore could not ultimately give rise to eutrophication.

From Science Daily
