Organic nitrogen gives new clue to biodiversity
Scientists have found that organic nitrogen is more important for plant growth than previously thought and could contribute to maintaining diversity in grasslands. view more (2006-04-12)
Follow the nitrogen to extraterrestrial life
The great search for extraterrestrial life has focused on water at the expense of a crucial element, say geobiologists at the University of Southern California. view more (2006-05-05)
Organic corn: Increasing rotation complexity increases yields
While demand for organic meat and milk is increasing by about 20% per year in the United States, almost all organic grain and forage to support these industries in the mid-Atlantic region is imported from other regions. To meet this demand locally, area farmers need information on expected crop yields and effective management options. view more (2008-05-29)
Prairie soil organic matter shown to be resilient under intensive agriculture
A recent study has confirmed that although there was a large reduction of organic carbon and total nitrogen pools when prairies were first cultivated and drained, there has been no consistent pattern in these organic matter pools during the period of synthetic fertilizer use, that is, from 1957-2002. view more (2009-01-16)
Tropical plants go with the flow ... of nitrogen
Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study that appears in the May 7 early online edition of The Proceedings of the National Academy of Sciences. view more (2007-05-08)
Illinois Soil Nitrogen Test Measures Microbial Nitrogen
Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. view more (2009-05-12)
Systems biology approach identifies nutrient regulation of biological clock in plants
Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status. view more (2008-03-17)
Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began. view more (2007-10-30)
How much nitrogen is too much for corn?
North Carolina State researchers recently discovered a test that quickly predicts nitrogen levels in the humid soil conditions of the southeastern United States. view more (2007-04-24)
Are comets at the origin of life on earth ?
For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great... view more...

The key to the lock that controls nitrogen fixation
"Bacteria that fix nitrogen only do so when they sense that there is very little nitrogen available in their environment," says Professor Ray Dixon (Project Leader at the JIC. "Normally the genes for nitrogen fixation are locked off and only unlocked and used when nitrogen levels in the environment fall. We have discovered a key... view more... (2004-11-04)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
Nitrogen research shows how some plants invade, take over others
Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. view more (2009-07-07)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. view more (2008-10-17)
Tropical forests leak nitrogen back into atmosphere, say scientists
In findings that could influence our understanding of climate change, a Princeton research team has learned that tropical forests return to the atmosphere up to half the nitrogen they receive each year, thanks to a particular type of bacteria that lives in those forests. view more (2006-05-23)
Organic & Biomolecular Chemistry
From January 2003 the Royal Society of Chemistry is merging J Chem Soc Perkin Transactions 1 & 2 to form: Organic & Biomolecular Chemistry. view more (2002-07-24)
Ultraviolet radiation induced flux of nitrogen oxides from pine needles
In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential... view more... (2003-03-14)
New strains of symbiotic nitrogen fixing Proteobacteria
Nitrogen is essential for plant growth. Legumes, representing the Earth's largest family of plants, can fix atmospheric nitrogen necessary for their growth thanks to an association with bacteria, the rhizobia. This ability proves to be particularly valuable when soils are poor in nitrogen. The nitrogen fixing symbiosis occurs in nodules,... view more... (2001-06-19)
How To Eliminate Nitrogen Narcosis Effects
We do not feel the nitrogen of air, and scientists do not believe that under normal pressure nitrogen can affect human organisms. However, being under water or in the altitude chamber nitrogen produces a different effect. Once the pressure is increased about four times, simulating the pressure which exists at the 30- meter depth, the first signs... view more... (2003-07-11)
