Harvesting immature corn and soybeans for forage after a killing frost

Paul Peterson, Jim Linn, and Dale Hicks, University of Minnesota Extension Service
Frost touched much of the state's corn and soybean acreage this past weekend. The degree to which the frost was a killing frost varies considerably, but a complete killing frost appears to have been the exception, not the rule. Where frost injury occurred without complete kill, it is too early to consider forage harvest because additional yield and forage quality accumulation is likely from surviving plant parts. However, where these crops were/are completely killed by frost before reaching optimum grain or even forage harvest maturity, harvesting as forage is a viable option. In addition, based on the delayed maturation of corn and soybeans to date, chances are good that there will many acres of these crops that will receive a killing frost before reaching maturity, so harvest as forage may still be one of the better options as the growing season plays out.
