Improving soil quality can slow global warming

Low-tech ways of improving soil quality on farms and rangelands worldwide could pull significant amounts of carbon out of the atmosphere and slow the pace of climate change, according to a new University of California, Berkeley, ...

Global worming: Earthworms add to climate change

(Phys.org)—Earthworms are long revered for their beneficial role in soil fertility, but with the good comes the bad: they also increase greenhouse gas emissions from soils, according to a study published Feb. 3 in Nature ...

Buried fossil soils found to be awash in carbon

Soils that formed on the Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's carbon cycle.

Energy crops impact environmental quality

Crop residues, perennial warm season grasses, and short-rotation woody crops are potential biomass sources for cellulosic ethanol production. While most research is focused on the conversion of cellulosic feeedstocks into ...

Life Underground Critical to Earth's Ecosystems

(PhysOrg.com) -- "I wonder if I shall fall right through the Earth!" mused Alice-in-Wonderland as she tumbled down the rabbit-hole." How funny it'll seem to come out among people that walk with their heads downwards! The ...

Biochar reduces nasty nitrous oxide emissions on farms

(Phys.org) —In the quest to decrease the world's greenhouse gases, Cornell scientists have discovered that biochar – a charcoal-like substance – reduces the nemesis nitrous oxide from agricultural soil on average by ...

Study advances science of carbon accounting

Determining with precision the carbon balance of North America is complicated, but researchers at Oak Ridge National Laboratory have devised a method that considerably advances the science.
