Organic farming combats global warming
Data from The Rodale Institute’s®
long-running comparison of organic and conventional cropping systems confirms that organic methods are far more effective at removing the greenhouse gas, carbon dioxide, from the atmosphere and fixing it as beneficial organic matter in the soil………..
The key lies in the handling of organic matter (OM): because soil organic matter is primarily carbon, increases in soil OM levels will be directly correlated
with carbon sequestration. While conventional farming typically depletes soil OM, organic farming builds it through the use of composted animal manures and cover crops………
"Agriculture and forestry are a very potent sink--they will make the emissions problem easier to get a handle on,”
Organic farming for carbon capture is also compatible with other environmental and social goals such as reducing erosion, minimizing impact on native
ecosystems, and improving farmer livelihoods.
