    Fred Magdoff is emeritus professor of plant and soil science at the University of Vermont. He was Plant and Soil Science Department chair for eight years and for two decades was the coordinator of the 12-state Northeast Region for the U.S. Department of Agriculture’s Sustainable Agriculture Research and Education (SARE) program. He is also a fellow of the American Society of Agronomy and the 2016 recipient of the Presidential Award of the Soil Science Society of America “for outstanding influence on soil science and enduring impact on the future of our science and profession.” He has worked on soil testing for nitrogen and phosphorus, the effects of manures on soil properties and crop yields, buffering of soil pH, and many other issues related to soil health. He lives in Burlington and Fletcher, Vt., with his wife, two dogs, a large garden, an occasional flock of chickens and a small herd of beef cows.

    Harold van Es

    Harold van Es is professor of soil science at Cornell University and served as chair of the Department of Crop and Soil Sciences. Born in Amsterdam, Netherlands, he moved to the United States for graduate studies and eventually a life and career in science. His current research, teaching and Extension efforts focus on soil health, digital agriculture and environmental statistics. He co-developed the widely used CASH soil health test and was the lead inventor of the Adapt-N technology, which was successfully commercialized and received the $1 million prize for the Tulane Nitrogen Reduction Challenge. He was the 2016 president of the Soil Science Society of America and is also a fellow of that society, as well as a fellow of the American Society of Agronomy. He and his wife live in Lansing, N.Y., where they raised three children.
