Corn Verification Crop Progress Update

🕔15:00, 22.Jul 2011

Irrigated Corn Verification Fields are nearly mature, but did require a final irrigation this week to provide ample moisture to sustain the crop to physiological maturity. Some slight root lodging also recently occurred, but otherwise harvest progress should commence soon. Late-planted dryland fields still have a long way to go and are under drought stress.
