Soil Management Solutions for GHG Reduction and CO₂ Storage

Back to Agriculture

Almost 33 million acres of forest around the world is cut down every year to make room for crop land, and the process removes up to half of the carbon in the soil. We can reverse some of these losses, though, with practices like leaving last season’s crop residue on the ground, planting cover crops, and controlling erosion. In the United States alone, if farmers widely adopted the best management techniques now available, they could return 70 to 220 million tons of carbon to farmland soil every year. Not only that, but some scientists think better-managed soil would produce more crops that resisted droughts and floods better. Research into things like high-residue crops, restoration of degraded land, and nitrogen fertilizer could help us make significant progress in reducing emissions from agriculture.
