Biochar is an agricultural product that both increases soil fertility and captures excess carbon out of the atmosphere. In this interview, Associate Professor Johannes Lehmann from Cornell University explains how Biochar is made and how it stores carbon. He also discusses the development of academic knowledge about Biochar and how well-developed is global production of the product. Johannes Lehmann was recently in Australia as a visitor of the US Studies Centre.
