Soils offer new hope as carbon sink
...rally emit about 10 times more greenhouse gas on a global
scale than the burning of fossil fuels. "So it is not surprising there is so much interest in a technology to create clean energy that also locks up carbon in the soil for the long term and lifts agricultural production," he said. The trials at...
