How a soil additive called biochar can help fight the climate crisis by locking away carbon for centuries. Presented by Deloitte.
A decade ago, Jim Doten was on a tour in Afghanistan with the Army National Guard searching for ways to help farmers improve soils depleted of nutrients and carbon.
Doten's biochar program in Afghanistan was short-lived, but the idea stuck. He's since convinced Minneapolis, Minnesota officials of biochar's value as governments search for ways to not only reduce greenhouse gas emissions but also remove them from the atmosphere. Doten first worked with the Shakopee Mdewakanton Sioux Community, a tribe in Minneapolis that owns a compost facility and develops urban gardens to promote food security. The city paid for biochar trucked in from Missouri to be mixed with compost.
