B-r-r-r. For many N. Wisconsin corn growers, the 2011 growing season ended overnight

For many northern Wisconsin corn growers, the 2011 growing season came to an end sometime during the night of Sept. 14, says Joe Lauer, UW-Madison Extension corn specialist. Corn in many areas had not reached physiological maturity and was killed prematurely. Corn is killed when temperatures are near 32 F for a few hours, and when temperatures are near 28 F for a few minutes.
