We have been blessed with an abundance of rain that has helped support corn development, and little irrigation has been needed. High temps mean water demand is higher too, and it is critical to not get behind on watering corn. Earliest planted corn is close to tasseling or tasseling which is peak demand time.

Nitrogen Loss in Saturated Soils
Continued saturated soils in some parts of the state have created concern with producers that N fertilizers that were already applied may be partially lost.
