Currently, farmers, legislators, and agricultural groups across the U.S. are urging the addition of phosphorus to the USGS Critical Minerals List. Phosphorus might not be a nutrient you think about every day, but without it, modern agriculture would struggle to feed the world.
In this episode of Fertilizer 101, host Morgaine Mertz-Myers sits down with Dr. Karl Wyant, Director of Agronomy at Nutrien, to explore the science, history, and future of phosphate fertilizers. From breaking down the difference between phosphorus and phosphate to touring Nutrien’s Aurora phosphate mine in North Carolina, we discuss why this essential mineral is so critical for farmers, crops, and national food security.
Along the way, Karl busts common myths about phosphate, explains the 4R nutrient stewardship approach, and makes the case for adding phosphorus to the U.S. Critical Minerals List. Whether you’re a farmer, policymaker, or simply curious about what keeps food on your plate, this episode will change the way you think about phosphate fertilizer.
