Steve Phillips Steve is the Nutrients for Life Foundation Professor of Crop Nutrition at Oklahoma State University, USA and President of the International Society of Precision Agriculture (ISPA). He earned his B.S. in agriculture from Cameron University in Lawton, Oklahoma, USA and his M.S. and Ph.D. from Oklahoma State University. He has over 25 years of experience in leading applied agronomic research and educational outreach programs aimed at improving the performance of diverse cropping systems worldwide through enhanced crop nutrition and precision agriculture (PA) technologies. He began his academic career at Virginia Tech as a soil fertility research and extension specialist, where he developed the first crop sensor-based nutrient management algorithms for the eastern USA. He later served as North American Director for the International Plant Nutrition Institute, leading global research and education programs for 12 years. Most recently, he was Principal Scientist at the African Plant Nutrition Institute, based in Morocco for four years, where he led PA research and extension activities across the continent. He is the founder of the African Association for Precision Agriculture and the African Conference on Precision Agriculture and has been an active ISPA member since 2010. Steve has authored over 200 scientific and extension publications and delivered keynote lectures in more than 20 countries. His research focuses on spatial and temporal drivers of crop yield response, fertility management in cropping systems, and multi-layer precision management effects on nutrient dynamics.
