Illinois Agronomist Emerson Nafziger addresses poor color of the corn crop in a recent post to The Bulletin. It is a website U of I Crop Scientists use to distribute important information about growing conditions, crop protection, and pest management in the state. Todd Gleason

Corn fields with poor color are probably suffering from a lack of oxygen rather than in need of an addtional nitrogen application. This is the conclusion of University of Illinois Agronomist Emerson Nafziger.

He writes in this week's bulletin, "As soils dry out in most areas of Illinois and temperatures stay warm, it’s likely that many fields with yellow corn plants will improve, in some cases rapidly. Late planting and warm temperatures do tend to favor top growth over root growth, but we expect that as leaves grow and start improve in color and as soil oxygen levels increase as soils dry, sugars will become more available to the roots as well as the tops, and this will further improve root uptake of nutrients."
