Biochar has been heralded as a key to revitalizing worn-out, weathered soils while increasing carbon sequestration and soil productivity. But is it too good to be true? We’ll explore scientific research to see if biochar could be used to improve non-productive soils to increase global food production in the face of population growth and limited arable land.
Kurt Spokas is a research soil scientist with the USDA Agricultural Research Service in St. Paul, Minn. He is also an adjunct professor at the University of Minnesota. His research focuses on the impacts of fungicides and biochar additions on the cycling of carbon, nitrogen, and other greenhouse gases, and practices to improve overall water quality.
