Cool, wet weather has created a yellowish cast across many newly emerged corn fields in Iowa. Symptoms like this are not unexpected considering the conditions seedlings were subjected to following planting. Seedbed conditions now are very different than what they were originally for corn planted weeks ago. The seedbed is cooler now and coupled with the recent cloudy skies and cool air temperatures we’ve experienced, the end result is a stressful environment for the young seedlings. Average soil temperatures on Sunday, May 7, 2006, were in the mid-50°s to mid-60°s across the state.
