2007 Lecturer | Dr. Andrew Sharpley

About the Lecturer

Dr. Sharpley is currently Professor in the Crop Soil and Environmental Science Department and Director of the Watershed Research and Education Center, University of Arkansas, Fayetteville, AR.

Dr. Sharpley has authored or coauthored more than 300 publications including 25 book chapters. He was a member of the National Academy of Science’s Committee on “Causes and Management of Coastal Eutrophication’ in 2000. He has been chair of Div. A-5 (Environmental Qualtiy) and has served as Associate Editor and Technical Editor of the Journal of Environmental Quality and Nutrient Cycling in Agroecosystems.


Dr. Sharpley is a Fellow of the ASA and SSSA and been awarded the ASA’s Environmental Quality Award (1994) and the SSSA’s Applied Soil Science Research Award (1998) and Soil Science Research Award (2003).


From 1978 to 1995, Dr. Sharpley was a Soil Scientist with the USDA Agricultural Research Service at the National Agricultural Water Quality Laboratory in Durant, OK and from 1995 to 2006 at the Pasture Systems and Watershed Management Research Unit, University Park, PA.

Dr. Sharpley’s research has greatly increased the basic understanding of the behavior and fate of P and N in agricultural systems and their impact on soil and water resources and has provided management options that are both economically practical and environmentally sound. He has developed a method to estimate P transported in runoff that is widely used in field research, assessment, and selection of agricultural management to reduce eutrophication potential in the USA, Europe, and Australia. This work has led to the development of an indexing system to identify soils, landscapes, and management systems vulnerable to P loss in runoff.


He received his B.S.degree in soil science and biochemistry from the University of North Wales, United Kingdom in 1973 and his Ph.D. from Massey University, New Zealand in 1977. He then completed a one-year post-doctoral appointment at the University of California – Davis.
