Plant nutrients are expensive, so optimizing available nutrients is critical to producing profitable crops. As such, Mark Alley says accessing residual nutrients are key to a winning crop nutrition plan.

In this presentation, the former Virginia Tech fertility specialist and consultant for Koch Agronomic Services explains how drought conditions influence residual soil nutrients, especially for nonmobile nutrients like phosphorus and potassium. He also explains the reactions of nutrients to soil clay and organic matter and how drought influences soil nitrogen.
