Potassium deficiency in corn and soybean is prevalent this year due to dry soil conditions. Potassium availability is reduced by dry soil and its movement to the root is also hindered thereby reducing plant uptake. Unfortunately, potassium's role in the plant is heightened when moisture is limiting further affecting plant growth and yield. To see the symptoms of potassium deficiency and more details on the role of potassium in plant growth see this video.
