Prodigious quantities of nitrogen from human waste flow into coastal waters, a study of nearly 135,000 watersheds reveals.
A new study challenges the assumption that cyanobacteria were the only major nitrogen fixers in the Proterozoic eon.
Food production is becoming less efficient at using nitrogen fertilizer, according to a review of global values. Excess nitrogen damages the environment and the climate.
Researchers compared the nitrogen removal potential by microbes in ditches that drained forested, urban, and agricultural lands and discovered that roadside ditches are important areas for removing nutrients.
Excess of a single nutrient, such as nitrogen, may boost plant productivity, but the imbalance leads to less efficient water use as plants scramble for the nutrients they lack.
Greenhouse gas emissions from sports fields may be scoring points for climate change.
Researchers track decades of nitrogen inputs and uptake across the United States, highlighting the need for policy to address the legacy effects of this essential nutrient and pollutant.
The release of reactive nitrogen into the environment is having severe and ongoing ecosystem, economic, and human health impacts. How can we reduce our nitrogen footprint?
In comparing soils from two tundra wetland landscape positions, landscape position is found to matter, and toeslopes are associated with higher greenhouse gas production.
