A conversation with harmful algal bloom expert Dr. Brian Lapointe reveals the dimensions of Florida’s algae problem, and some possible solutions.
Early Lake Erie region settlers viewed the Black Swamp as an obstacle to be overcome. One researcher says bringing part of its wetlands back may help the region, not hurt it.
The IL Nutrient Loss Reduction Strategy is generating interest and improving water quality by reducing nutrient runoff into Illinois watersheds.
Research modeling the path of nitrogen in soil and groundwater shows it will take longer for nitrogen recovery to unfold—but also shows efforts are working.
Armed with smartphones, test strips, and sample containers, citizen scientists are testing water for nitrates in Iowa, and assisting researchers in the process.
Bioreactors can help protect the Chesapeake Bay Watershed from excessive nitrates in water from agricultural runoff while protecting nitrogen-rich soil.
An effort to mitigate soil acidity in Hubbard Brook Experimental Forest took a surprise turn when, 10 years later, nitrogen levels surged in nearby streams.
A research buoy operated by Ohio State University’s Stone Lab is deployed in Lake Erie and keeping an eye on water quality around Put-in-Bay, Ohio. Data from the platform are available online in real time. Some of...
In the past 100 years, agricultural and industrial activity have tripled the amount of nitrogen in the atmosphere, researchers have found. One of the effects of all of this excess nitrogen is a loss of biodiversity, as...
Federal agencies are preparing for a price drop in nutrient sensor tech that could bring a boom in the number of instruments deployed across the nation.
Florida State University scientists lead a sampling effort to study low ocean nitrogen fixation in the South Pacific. The key, they believe, is iron.
An overabundance of nutrients is straining nature’s symbiotic relationships, according to a University of California – Santa Barbara press release. Researchers say increased levels of nitrogen from nitrogen-laced fertilizer and burning fossil fuels are changing how co-dependent...
Researchers at the University of California, Santa Cruz, have linked the declines of a number of endangered species with the prevalence of nitrogen pollution, according to a release. Their finds came after a large-scale survey of species...
With more support for dual nutrient management strategies, Wright State researchers show us how they’re studying nitrogen’s role in runoff and algal blooms.
Several years into a shellfish restoration project in Long Island’s Great South Bay, officials with the Nature Conservancy of Long Island began to notice that many of the clams they had stocked weren’t making it, according to...
Nutrient and sediment levels in Chesapeake Bay have declined over the last few years, but the bay's overall health remains poor
