## Resource

What happens when crops remove phosphorus and potassium from the soil, and what does it take to replenish them? In this episode, we're in the classroom at Mississippi State University sitting down with Dr. Vaughn Reed to explore how to manage nutrient removal and replenishment by thinking about your soil like a bank account. From what's immediately available to the crop versus what takes time to become available, to how different soils respond to replenishment and the economics of rebuilding fertility levels, we break down how phosphorus and potassium behave in the soil and how to think about removal and replacement across soil types. Plus, Dr. Reed shares what growers should consider when making replenishment decisions under tight margins, and answers questions about removal and replacement from across the classroom.
