WebSince 2004, we have been working on quantifying the global potential of biochar systems to mitigate climate change. Previous projects include studies on the persistence of biochar, its effects on mineralization of other organic carbon in soil, nutrient leaching, gaseous loss, signaling between microorganisms and plants, as well as electrochemistry. Webcarbon ring structures in biochar and placed in soils where they persist for hundreds or thousands of years. When deployed on a global scale through the conversion of gigatonnes of biomass into biochar, studies have shown that biochar has the potential to mitigate global climate change by drawing down atmospheric GHG concentrations
