Johannes Lehmann, professor of soil biogeochemistry and soil fertility management at Cornell University, received his graduate degrees in Soil Science at the University of Bayreuth, Germany. During the past 20 years, he has focused on nano-scale investigations of soil organic matter, the biogeochemistry of black carbon and sequestration in soil. He is principal investigator of projects focusing on climate-smart agriculture, on developing fertilizers from waste and on soil carbon sequestration. Dr. Lehmann is a member of the steering group of the International Soil Carbon Network, has testified in the US congress, briefed the President’s council of advisors, was part of Workgroup 2 on Monitoring and Assessment of Sustainable Land Management of UNCCD, and serves on the Technical Management Advisory Committee of USAID legume program. Dr. Lehmann has authored more than 200 journal publications, has been named ISI Highly Cited Researcher and is editor-in-chief of the journal Nutrient Cycling in Agroecosystems.

I am interested to advance our 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 implications for climate change, food security and environmental pollution.
The strong background in the chemistry, biology and physics of soils and its cycles provide the basis for the development of intelligent solutions for sustainable soil and land use management. The most exciting examples include the discovery of stabilization mechanisms of organic matter in soil nano-structures, the cycles of pyrogenic carbon and the development of a biochar soil management technology.
