It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. (wikipedia.org)
These fertilizers contain high amounts of phosphorus and nitrogen, which results in excess amounts of nutrients entering the soil. (wikipedia.org)
Nitrogen, phosphorus and potassium are the "Big 3" primary nutrients in commercial fertilizers, each of these fundamental nutrients play a key role in plant nutrition. (wikipedia.org)
Includes nitrogen, ammonia, and phosphorus which can reduce oxygen in surface waters, encourage the growth of harmful algal blooms, and contaminate drinking water. (cdc.gov)
The oxygen conditions are good in the Archipelago Sea, but phosphorus concentrations were significantly higher than in the previous winter. (ilmastodieetti.fi)
The highest phosphorus concentrations were observed in the southern part of the Archipelago Sea, where more nutrient-rich water flows in from the Baltic Proper. (ilmastodieetti.fi)
Unusually robust spring floods in the U.S. Midwest are flushing agricultural runoff-namely, nitrogen and phosphorus-into the Gulf and spurring giant algal blooms, which lead to dead zones, or areas devoid of oxygen that occur in the summer. (nationalgeographic.com)
The results suggest further studies using more robust experimental designs are needed to explore lake-specific dual nutrient management strategies for preventing cyanobacterial blooms in this phosphorus-rich hypereutrophic lake and possibly other hypereutrophic lakes. (cdc.gov)

These findings are significant because there has long been scepticism in the scientific community that microplastic concentrations in the ocean are high enough to have any impact on nutrient cycling", says Dr Karin Kvale "Our study shows that even at levels present in the ocean today, it may already be the case if zooplankton replace some of their natural food with microplastics.

Scientists generally agree that the Bay's critters need dissolved oxygen concentrations of 5.0 mg/L or more to live and thrive. (chesapeakebay.net)
Worms and clams that live in the Bay's muddy bottom-where oxygen levels are naturally low-need dissolved oxygen concentrations of at least 1 mg/L. (chesapeakebay.net)
