Can farmers increase production while reducing greenhouse gas emissions, simply by mixing charcoal in with their soil? That what Albert Bates argues in The Biochar Solution: Carbon farming and climate change. Other guests include Julie Major, Faculty Lecturer at McGill University and an independent consultant who has worked with biochar for seven years, and Vermonter Jock Gill, who is experimenting with biochar at Shelburne Farms and promoting heating buildings while producing biochar for soils.

Links mentioned during the show include an article about biochar on dairy farms in Progressive Dairyman and a simple stove for outdoor cooking and biochar production.
