Rhode Island Nitrogen Cycle Differs In Bay And Sound
2014-04-29 17:17:11

Brown University A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences between bay and sound sediments, but that raises new questions about what’s going on in the Bay to account for those. Rhode Island’s geography is famously small, but new measurements of the nitrogen cycle in its waterways suggest that...

Study May Resolve Controversy Over Nitrogen’s Ocean Exit Strategies
2014-04-14 12:19:53

By Catherine Zandonella, Princeton University A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington. The debate centers on how nitrogen — one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide — becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused...

Farmers may be able to help reduce emissions of the greenhouse gas nitrous oxide (N2O) by incorporating copper into crop fertilization processes – according to new research from the University of East Anglia. Global agricultural emissions of the gas have increased by 20 per cent in the last century as a result of widespread use of nitrogen-based synthetic fertilizers. But new research into the processes of nutrient cycling published today reveals how farmers could mitigate the effects...

The Oceans Nitrogen Puzzle

Max-Planck-Gesellschaft Nitrogen isotope effects by anammox deciphered A team of scientists from the Max Planck Institute for Marine Microbiology, the University of Basel, and Radboud University Nijmegen has now revealed the details of an important microbial process regulating the global nitrogen budget in the oceans. They present their results in the Proceedings of the National Academy of Sciences of the United States of America. Every organism needs nitrogen to survive and...

Max Planck scientists unravel key pathway in the nitrogen cycle The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged by this process. A group of specialized bacteria perform the anammox reaction, but so far scientists have been in the dark about how these bacteria could convert ammonia to nitrogen in the complete...

Study examines the disposal of animal waste in large-scale swine productionNorth and South Carolina have seen a steady increase in swine production over the last 15 years. In North Carolina alone, swine production generates approximately a quarter of the state's gross farm receipts. The presence of so many large-scale pig farms leads to the problem of proper animal waste disposal.The most common practice in the Carolinas is storing animal waste in anaerobic lagoons. They are primarily used to...

Excess nitrogen from agricultural and urban lands is contaminating groundwater, streams, lakes and estuaries, where it causes harmful algal blooms and contributes to fish kills. Cost-effective approaches to removing this nitrogen from croplands and urban stormwater runoff before it reaches sensitive water bodies have been elusive. But simple and inexpensive technologies are on the horizon. A recent scientific workshop on denitrification brought together ecologists, engineers and policy...

Nitrogen fixation in the Atlantic Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. Their findings have potentially important implications for understanding global climate, both past and future. Nitrogen is an essential...
