Dr. Sampson Agyin-Birikorang has more than 25 years of experience in soil science at the university level and through agricultural extension services. As an IFDC systems agronomist since 2010, Agyin-Birikorang conducts interdisciplinary research focused on improving nutrient use efficiency and facilitating the transfer of innovative agro-technologies. His activities involve all facets of agricultural research including design and implementation of laboratory, greenhouse and field trials in the USA and developing countries. Agyin-Birikorang has also held research and teaching positions at the University of Florida, Gainesville (USA), Montclair State University, New Jersey (USA), and University of Ghana in Accra. He has conducted extensive research in the following areas: the enhancement of phosphorus availability from phosphate rock in highly weathered tropical soils; nutrient management, particularly nitrogen and phosphorus, in agricultural fields in sensitive watersheds; and shifts in land use and/or management practices on nitrogen dynamics and cycling in soils. Agyin-Birikorang’s current research and extension program is focused on activated phosphate and ISFM. He has provided technical assistance and consultancy services to several projects in sub-Saharan Africa and southern Asia on principles and practices of ISFM. Agyin-Birikorang has authored or co-authored numerous refereed and non-refereed publications, papers and reports and made numerous presentations at national and international meetings and conferences. He holds a doctorate in soil and water science from the University of Florida and a master’s degree in soil science from the University of Ghent in Belgium. He earned a bachelor’s degree in soil science from the University of Ghana.
