What are the soil carbon sequestration potentials of biochar and enhanced weathering?

In our sixth webinar of 2022, “Biochar and Enhanced Weathering,” we will discuss two emerging soil sequestration technologies with leading U.S. experts. Dr. Johannes Lehmann (Cornell University) will discuss the path ahead for biochar utilization. Dan Maxbauer (Carleton College) will describe the technical potential for crushed silicate rocks to sequester CO2 through enhanced mineral weathering.

Time: September 13th 2022, 3:00 PM Eastern.

Dan Maxbauer is an Assistant Professor in the Geology Department at Carleton College where he teaches courses on climate science and the carbon cycle. His most current research is focused on carbon dioxide removal through enhanced weathering in agricultural systems. Along with undergraduate students from Carleton, Dan is overseeing an agricultural field trial for enhanced weathering through applications of crushed basalt and a commercially available slag fertilizer.

Johannes Lehmann, Liberty Hyde Bailey professor of soil biogeochemistry and soil fertility management at Cornell University, received his graduate degrees in Soil Science at the University of Bayreuth, Germany. His research focuses on nano-scale investigations of soil organic matter, the biogeochemistry of pyrogenic carbon and sequestration in soil, sustainable soil management, climate change, and the circular economy. Dr. Lehmann is a member of the steering group of the International Soil Carbon Network, has testified in the US congress, and briefed the President’s council of advisors. Dr. Lehmann has authored more than 250 journal publications, has been named Highly-Cited Researcher by Thomson Reuter since 2014, is member of the German National Academy of Sciences (Leopoldina) and Fellow of the Soil Science Society of America, he was named Humboldt Fellow and Hans-Fischer Senior Fellow of the Institute of Advanced Studies at the Technical University of Munich.
