Johannes Lehmann is the Liberty Hyde Bailey professor of soil biogeochemistry and soil fertility management at Cornell University. He received his graduate degrees in Soil Science at the University of Bayreuth, Germany. He 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 200 journal publications, was named Highly-Cited Researcher by Thomson Reuter in 2014-2016, is member of the German National Academy of Sciences and Fellow of the Soil Science Society of America, was named Hans-Fischer Senior Fellow of the Institute of Advanced Studies at the Technical University of Munich, and serves as editor-in-chief of the journal Nutrient Cycling in Agroecosystems.
Dr. Lehmann is interested to advance general understanding of biogeochemical cycles of carbon and nutrient elements in soil, providing important insight into regional and global element cycles such as the carbon or sulfur cycle. This field of research has global and local relevance with important implications for climate change and environmental pollution. The most exciting examples include the discovery of stabilization mechanisms of organic matter in soil nano-structures and the development of a biochar soil management technology that improves soil fertility, sequesters carbon and reduces off-site pollution. Recent efforts include the combination of bio-energy and biochar applications to soil, which offer the opportunity to develop a carbon-negative energy technology which at the same time improves the environment.
He is teaching course on Nutrient Management in Agroecosystems and Carbon and Nutrient Cycling in Natural and Managed Ecosystems, Environmental Science Colloquium and support of introductory courses in Environmental Sciences, Traditional Agriculture in Developing Countries and Tropical Cropping Systems.
