Mark David

Mark B. David is a Professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois at Urbana-Champaign and has been on the faculty since 1985. He studies nitrogen and phosphorus cycling in agricultural fields, losses to streams and rivers, and methods to reduce these losses such as fertilizer application timing, cover crops, drainage water management, constructed wetlands, and bioreactors. His research team conducts long-term monitoring of water quality in several tile-drained watersheds in east-central Illinois to better understand the mechanisms of nutrient loss and to evaluate the effectiveness of nutrient loss reduction methods. He has degrees from Penn State University, the University of Maine, and the State University of New York, College of Environmental Science and Forestry.
