Donald Lewis Sparks


Donald L. Sparks is an American soil scientist, currently Unidel S. Hallock duPont Chair of Soil and Environmental Chemistry, Francis Alison Professor, Director, Delaware Environmental Institute, University of Delaware,
and Hagler Fellow in the Hagler Institute for Advanced Study at Texas A&M University.

Biography

Sparks received a B.S. in Agronomy in 1975 and an M.S. in Soil Science in 1976 from the University of Kentucky, Lexington, Kentucky, and a Ph.D. in Soil Science in 1979 from Virginia Polytechnic Institute and State University, Blacksburg, Virginia.
Sparks was president of the Soil Science Society of America in 2000, and the International Union of Soil Sciences from 2002-2006. For three years he chaired the U.S. National Committee for Soil Sciences, which advises the National Academy of Sciences.
Sparks was an early leader in promoting critical zone science and was principal investigator of one of the first six National Science Foundation supported Critical Zone Observatories, the Christina River Basin Critical Zone Observatory.
In 2019-2020, he served on the National Academies Committee on Catalyzing Opportunities for Research in the Earth Sciences, a study focused on developing research recommendations for the National Science Foundation for the decade 2020-2030.
In 2021, the European Geosciences Union awarded Sparks the Philippe Duchaufour Medal for his influential research on soil chemistry and physical chemistry that helped develop the field of soil science. His work has transformed the understanding of kinetics of soil chemical processes, surface chemistry of soils and soil components, and the physical chemistry of soil potassium.

Awards and honors

He is a Fellow of the American Association for the Advancement of Science, the Geochemical Society, the European Association of Geochemists, the American Society of Agronomy, and the Soil Science Society of America. He has received the Geochemistry Medal from the American Chemical Society, the Liebig Medal from the International Union of Soil Sciences, the McMaster Fellowship from the Australian Commonwealth Scientific and Industrial Research Organization, the Einstein Professorship from the Chinese Academy of Sciences, and the Pioneer in Clay Science Award from the Clay Minerals Society. He was President of the Soil Science Society of America and the International Union of Soil Sciences.
