Episode 326: Exploring Soil Organic Matter with Dr. Johannes Lehmann

We have only recently begun to understand the true nature of soil organic matter. In this episode of Voices from the Field, NCAT Sustainable Agriculture Specialist Nina Prater is joined by Dr. Johannes Lehmann, a Cornell University professor with the School of Integrative Plant Science – Soil and Crop Sciences Section as well as the Department of Global Development. They talk about misconceptions around soil humus and explore new ways to look at the organic components of the soil. They also discuss a number of other issues, including the carbon cycle, the importance of diversity, and the challenges of creating a circular economy.
