In this week’s Boots In The Field Report Ken covers nitrate levels, carbon penalty, cutworm, rootworm, and armyworm flights, and crop deficiencies showing up. He breaks down the difference in nitrogen, sulfur, and zinc deficiencies and how they present in the corn plant. Adding nitrogen to a sulfur deficiency can make the problem worse, so it is important to know which one you are facing. He also covers yellowing beans fighting the carbon penalty and why replant beans might be showing it more than older beans.
