Latest Nitrogen cycle Stories
The oceans of the past were quite different than the ones we see today. Ocean temperatures are increasing due to global warming, and these increases are harming marine food webs. Coastal dead zones are also being created by the run-off from fertilizers.
A new global-scale modeling study that takes into account nitrogen – a key nutrient for plants – estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen.
Despite widespread use of fertilizers and nitrogen emissions by industrial processes, the amount of atmospheric nitrogen has remained consistent over the past 500 years, according to a new study in Nature.
A new study by researchers at BYU, Duke and the USDA finds that soil plays an important role in controlling the planet’s atmospheric future.
Chemists from the University of California, Berkeley have discovered evidence of a link between increased fertilizer use and a rise in atmospheric nitrous oxide, a major greenhouse gas.
A new paper by researchers from the University of Georgia and Princeton University sheds light on the critical part played by a little-studied element, molybdenum, in the nutrient cycles of tropical forests.
The nitrogen cycle has been profoundly altered by human activities, and that in turn is affecting human health, air and water quality, and biodiversity in the U.S.
Nitrogen is both an essential nutrient and a pollutant, a byproduct of fossil fuel combustion and a fertilizer that feeds billions, a benefit and a hazard, depending on form, location, and quantity.
Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm.
The tiny phytoplankton Emiliania huxleyi, invisible to the naked eye, plays an outsized role in drawing carbon from the atmosphere and sequestering it deep in the seas.
