Soil on organic farms can hold more carbon, says study

Research by Northeastern University indicates soil on organic farms contains more of a key component for sequestering carbon than soils on other farms, said the Organic Trade Association. The trade group said the study, which compared samples of soil from across the country, "provides a significant proof point that organic agricultural practices build healthy soils and can be part of the solution in the fight on global warming."

Summer heat wave: Is corn ‘sweat’ part of the problem?

Midwesterners sweltering in hot, muggy weather this summer are hearing that their agricultural mainstay—corn—is at least partly responsible for their discomfort. This is because the corn plants transpire, drawing moisture into the air, which adds to the humidity. One can think of transpiration as the crop “sweating”—the plant’s means of staying cool.

Methane-producing microbes found in California rocks

For the first time, scientists have found methane-producing microbes living near the earth's surface, rather than in volcanic vents in the ocean floor, says the American Geophysical Union. The study "also shows the newly-discovered microbes are likely capable of using carbon dioxide to produce methane — a finding that could have implications for future carbon sequestration projects."

To mitigate climate change, USDA allots $72 million for carbon storage in soil

Agriculture Secretary Tom Vilsack announced a $72.3 million allocation within the cost-sharing Environmental Quality Incentive Program for activities that boost carbon storage in healthy soil. Vilsack unveiled the initiative during a one-year review of USDA's Climate Smart program to help meet U.S. pledges to mitigate climate change.

Report offers guidelines for calculating carbon storage

The Agriculture Department released a report that, "for the first time, provides uniform scientific methods for quantifying the changes in greenhouse gas emissions and carbon storage from various land management and conservation activities."
