Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the... view more (2006-03-09)

Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere.   view more (2007-12-12)

Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.   view more (2008-01-03)

Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil.   view more (2007-03-13)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

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)

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)

An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon... view more (2003-05-22)

Nitrogen study may improve ecological predictions
The pattern of nitrogen release from decaying plant material is remarkably similar and predictable across the planet, researchers have concluded in a new study, which should make it easier to understand nutrient dynamics, vegetation growth, estimate carbon release and sequestration, and better... view more (2007-01-19)

Before selling carbon credits, read this
Storing carbon in agricultural soils presents an immediate option to reduce atmospheric carbon dioxide and slow global warming.   view more (2007-05-21)

Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't.   view more (2008-03-12)

Study helps clarify role of soil microbes in global warming
Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere.   view more (2008-10-29)

Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth.   view more (2008-06-03)

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)

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)

Can biofuels be sustainable?
With oil prices skyrocketing, the search is on for efficient and sustainable biofuels. Research published this month in Agronomy Journal examines one biofuel crop contender: corn stover.    view more (2008-08-20)

Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions.   view more (2008-11-20)

Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science.   view more (2007-10-26)

The effect of transgenic nematode resistance on non-target organisms in the potato rhizosphere
A paper published today in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the... view more (2002-11-26)

Satellites Help Map Soil Carbon Flux
Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and The University of Tennessee investigated quantifying soil carbon changes over large regions.   view more (2008-03-26)

Carbon sinks: Issues, markets, policy
With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2.   view more (2008-09-29)

Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions.   view more (2008-02-25)

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)

New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate.   view more (2007-12-12)

Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.   view more (2008-10-08)
