FAYETEVILLE, Ark. -- The International Plant Nutrition Institute recently announced that it has named University of Arkansas Professor Andrew N. Sharpley as the winner of the 2010 IPNI Science Award, which included a $5,000 monetary award.

Sharpley is a professor of crop, soil and environmental sciences in the statewide University of Arkansas Division of Agriculture and Dale Bumpers College of Agricultural, Food and Life Sciences.

“Dr. Sharpley provides international leadership in determining the fate and transport of phosphorus in agricultural systems and its environmental impact. He led development and refinement of a phosphorus index to identify agricultural fields at greatest risk for nutrient loss and needing remediation,” said Terry L. Roberts, president of IPNI.

Sharpley is co-director of the Division of Agriculture’s Watershed Research and Education Center in Fayetteville and co-chair of the Division’s statewide Environmental Task Force.

The phosphorus index helps farm planners advise farmers about the water quality implications of management decisions and alternative practices, Roberts said. His research has demonstrated that effective strategies of fertilizer, manure and tillage use can achieve production goals and protect water quality, Roberts added.

Born in Manchester, England, Sharpley received his B.S. degree from the University of North Wales and a doctorate in soil science at Massey University in New Zealand.

Sharpley joined the University of Arkansas Division of Agriculture in 2006. From 1995 to 2006, he was a soil scientist with the U.S. Department of Agriculture-Agricultural Research Service at University Park, Penn., and adjunct professor at Pennsylvania State University. From 1985 to 1995, he was a USDA-ARS soil scientist at Durant, Okla.

Sharpley is a 2008 inductee of the USDA-ARS Hall of Fame, “For pioneering nutrient research leading to the development of agricultural management practices and strategies that are used nationally and internationally to protect water quality.” He is also a fellow of the American Society of Agronomy and the Soil Science Society of America.
