 Dr. Phillip R. Owens is the Research Leader and Research Soil Scientist with the USDA, Agricultural Research Service, Dale Bumpers Small Farms Research Center in Booneville, Arkansas. Prior to his arrival in 2016, He was an Associate Professor of Pedology/Soil Geomorphology in the Department of Agronomy at Purdue University. After receiving his B.S. and M.S. at the University of Arkansas, he completed a Ph.D. in soil science from Texas A & M University in 2001. Upon completion of his Ph.D., he worked as a Research Soil Scientist with USDA-ARS at Mississippi State University. Dr. Owens research interests include soil and landscape processes, hydropedology and digital soil mapping related to land-use management. Dr. Owens research focuses on understanding soils and soil function within the Southeast Area, as well as, internationally. He is currently leading a project to map soil properties and soil function at 30 m resolution for El Salvador, Honduras, Nicaragua, Guatemala and the State of Oaxaca. He is the past Chair of the Pedology Division of the Soil Science Society of America, Past Associate Editor of Soil Science Society of America Journal, Former Co-Chair of New Technologies in Soil Survey Committee, Facilitator of the IUSS Universal Soil Classification System Committee, and as a former member of the National Soil Survey Advisory Board.
