Corn can handle a lot of moisture, but standing in water multiple days can ruin the yield potential of even the hardiest plants.
With any luck, the excess moisture Midwest farmers have recently endured will abate and allow corn growth to resume.
If the soil is able to dry out, some of the potential yield will be restored if developing ears have not been compromised too badly, according to Emerson Nafziger, University of Illinois Extension corn specialist.
He says plants standing in water suffer from a lack of oxygen in the roots.
“Applying foliar forms of nitrogen or dry forms such as urea will not do much good until the water goes away and the roots start to take up oxygen,” he writes in the June University of Illinois Integrated Pest Management newsletter.
