Civil Eats - When it comes to mitigating the worst impacts of climate change, keeping excess carbon out of the atmosphere is the prime target for improving the health of our planet. One of the best ways to do that is thought to be locking more of that carbon into the soil that grows our food.
The scientific community has been actively debating whether organic farming methods can provide a promising solution. A 2010 paper published in the journal Ambio found that research about increased carbon sequestration due to organic farming methods was inconclusive, while a 2012 study in the Proceedings of the National Academy of Sciences (PNAS) found increased carbon sequestration in organic farm soils—though a 2013 letter in the PNAS disputed those findings, arguing that there were no carbon sequestration benefits related to organic farming.
A new study from Northeastern University and nonprofit research organization The Organic Center (TOC), though, has reached a different conclusion: Soils from organic farms had 26 percent more potential for long-term carbon storage than soils from conventional farms, along with 13 percent more soil organic matter (SOM).
