The decisions you make from now until harvest can either protect your return on investment or quietly erode it. In this episode of Crop Cast, Sean Nettleton, Jaren Schley, and Mason Claude break down the science behind late-season fertility, exploring nutrient availability, nutrient mobility, and how to interpret the data that matters most. They discuss practical strategies for making targeted in-season decisions that support grain fill, improve nutrient efficiency, and maximize the value of every input. If you're looking to finish the season stronger while making informed, data-driven management decisions, this conversation is one you won't want to miss.
