Dr. David E. Clay received a B.S degree from the University of Wisconsin (Madison), M.S. Degree from the University of Idaho, and Ph.D. from the University of Minnesota. Currently, he is Professor of Soil Science at South Dakota State University. He has served on the Editorial Board for the Agronomy Journal in a number of roles including Associate Editor, Technical Editor, and Editor. In addition, he is an Editor or author for 13 books and has published over 250 papers. Dr. Clay’s research goal is to develop and test sustainable precision agricultural management systems that enhance environmental quality, maintain rural economies, and improve energy and economic self-sufficiency.
Based on his research, teaching, and service responsibilities he has received a number of awards including two papers that awarded paper of the year, being twice selected for the ASA precision Systems Impact award, being selected twice for the SDSU College of Agriculture and Biological Sciences Outstanding Researcher, editor on three books that were awarded excellence in extension materials greater than 15 papers, selected as a Fellow of the American Society of Agronomy in 2007, being awarded the 2009 PrecisionAG Award of Excellence in Education and research, and being awarded the SDSU F.O. Butler Award for Excellence in Research.
Area(s) of ResearchMy research goal is to develop and test sustainable agricultural management systems that enhance environmental quality, maintain rural economies, create wealth and jobs, improve soil health, and lead to energy self-sufficiency. Specific research projects include the development of: (i) a conceptual understandings on how complex interactions among weeds, crop genetics, soils, topography, water, insects, diseases, and nutrient cycling influence crop productivity, profitability, and energy efficiency over landscapes; (ii) remote sensing techniques for assessing C storage and N and water stress in crop plants; (iii) new techniques for assessing the impact of management on system resilience; and (iv) precision farming equations for improved management. Principle obstacles to this research has been: (i) the linking of information collected at cellular or plant scales with higher organizational levels; (ii) developing analysis tools that quantitatively define the impact of stress on plant growth, (iii) mathematically defining how different limiting factors interact to influence yield, and (v) developing experimental approaches to solve multivariate problems. We have used simulation models, remote sensing, tracking stable isotopes pulses, microarray analysis, detailed soil and plant measurements, and natural abundance stable isotope approaches in our research. I am committed toward increasing the adoption of technologies that can improve agricultural profitability and environmental sustainability. To achieve this goal I believe that we need to research the barriers to adopting technologies that clearly have economic and environmental benefits. I am committed to convert agricultural research into tools that producers can use to increase their profitability.
