 Dr. Carl H. Bolster is a Research Hydrologist and Lead Scientist (ARS Research Project # 5040-12630-006 “Developing Agronomically and Environmentally Beneficial Management Practices to increase the Sustainability and Safety of Animal Manure Utilization”) with the USDA-ARS Food Animal Environmental Systems Research Unit in Bowling Green, KY USA. He also recently served as Chapter Lead for the Agriculture, Food Systems, and Rural Communities chapter of the Fifth National Climate Assessment (Agriculture, Food Systems, and Rural Communities (globalchange.gov). Dr. Bolster is actively involved with the Fertilizer 4 Life Initiative (Fertilize 4 Life - Global Food Systems Institute - University of Florida, Institute of Food and Agricultural Sciences - UF/IFAS (ufl.edu)), the USDA Legacy Phosphorus Project USDA Legacy Phosphorus Project (arcgis.com), and the Fertilizer Recommendation Support Tool (Fertilizer Recommendation Support Tool (soiltestfrst.org)). The overall goal of Dr. Bolster’s research is to improve our understanding of the fate and transport of phosphorus in agroecosystems. Specific objectives are: (1) understanding factors controlling the fate and transport of phosphorus in agricultural soils and to evaluate and update.
