Atmosphere threatened by pollutants entering ocean, prof says
A large quantity of nitrogen compounds emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere.   view more (2008-05-16)

UMCES-led research team quantifies nutrient pollution reductions from urban stream restoration
A team of researchers led by University of Maryland Center for Environmental Science researcher Dr. Sujay Kaushal has been among the first able to quantify the amount of excess nitrogen removed from an urban stream during environmental restoration projects.   view more (2008-05-01)

Organic farming produces same corn and soybean yields as conventional farms, but consumes less energy and no pesticides, study finds
Organic farming produces the same yields of corn and soybeans as does conventional farming, but uses 30 percent less energy, less water and no pesticides, a review of a 22-year farming trial study concludes.   view more (2005-07-14)

New Sighting of Soil-Borne Wheat Mosaic Virus (SBWMV)
Following investigation of a sample sent to NIAB and Central Science Laboratory (CSL), two new sites in Kent have been identified with soil-borne wheat mosaic virus (SBWMV). The virus was identified in the UK in Wiltshire for the first time in 1999 and this occurrence appears to have no connection... view more (2000-08-08)

Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them... view more (2005-05-05)

Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species.   view more (2008-10-07)

Experiment Demonstrates 110 Years of Sustainable Agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods.    view more (2008-09-30)

Invititation to the Media - Soils as carbon sinks-a breathing space in the race against global warming?
Can we use land carbon sinks as a way to buy time for the restructuring of our energy generation? "We estimate soil carbon sinks could mitigate 8% of the EU`s emissions if major changes were made in land use and agricultural management ," says Professor David Powlson of IACR Rothamsted. However;... view more (2002-06-26)

Sowing a future for peas
New research from the John Innes Centre and the Central Science Laboratory could help breeders to develop pea varieties able to withstand drought stress and climate change.   view more (2008-09-17)

New-Caledonia: is the chromium present in soil toxic for crop plants ?
Nearly one-third of the surface area of New Caledonia bears outcrops of ultramafic rocks containing high levels of heavy metals, such as nickel and chromium. The soils derived from these formations, bearing high concentrations of these metals, are however poor in mineral elements essential for... view more (2003-05-23)

Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen.   view more (2008-09-04)

Piecing together the cyanobacteria puzzle
Blue green algae are significant species in the global carbon cycle because they transform nitrogen gas from the atmosphere into a useable nutrient, enabling photosynthesis in nutrient-poor waters.   view more (2007-07-11)

Drought reduces nitrogen-fixing in legumes
In drought conditions, the capacity for retaining carbon in legume nodules is limited and this may be the reason why there is a drop in nitrogen-fixing in legumes under these conditions. This was the conclusion of Mar'­a Dolores G'Ħlvez in defending her PhD thesis at the Public University of... view more (2005-02-04)

Nitrogen in the air feeds the oceans
A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow?   view more (2005-08-11)

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... view more (2001-06-19)

Could seaweed clean up DDT?
Adding small amounts of seaweed to contaminated soil could prove to be a natural and effective way of breaking down the toxic pesticide DDT, according to new research in the Journal of Chemical Technology and Biotechnology. A British biologist, Ian Singleton, worked with colleagues in Australia and... view more (2004-04-13)

Fertilizers - a growing threat to sea life
New study on landscape around Chesapeake Bay says imbalance in nitrogen cycle is damaging water quality and fish populations.   view more (2008-10-22)

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood.   view more (2005-10-10)

Asthmatic children in multi-family housing hit by indoor nitrogen dioxide
Children with asthma living in multi-family housing who are exposed to certain levels of indoor nitrogen dioxide, a poisonous pollutant byproduct of gas stoves and unvented heaters, are more likely to experience wheeze, persistent cough, shortness of breath and chest tightness.   view more (2006-02-01)

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... view more (2008-05-29)

Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among... view more (2004-03-18)

Soil nutrients shape tropical forests, large-scale study indicates
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them.   view more (2007-01-12)

Researchers Find That Cattle Tuberculosis Remains in Fields For Up to 4 Months
Researchers from the University of Warwick's Department of Biological Sciences have found evidence that bovine tuberculosis remains in fields for up to 4 months. This means that long after an outbreak of bovine TB on a farm healthy cattle may still be exposed to the disease from pasture that had... view more (2002-04-19)

Groundbreaking research in Scotland
A £5.85 million pound study of the soil in the Cheviot Hills has finally come to an end, producing a huge wealth of new information for scientists.   view more (2004-03-31)

When light helps symbiont bacteria associate with plants to fix nitrogen
Certain leguminous plants which live in rice fields have the exceptional feature of forming nitrogen-fixing nodules on their stem surfaces. These contain symbiotic bacteria capable of using light as an energy source. Although it had been suspected that bacterial photosynthesis played a role in this... view more (2001-01-26)
