Abstract

Extended periods of unseasonably warm temperatures during the winter months can lead to reduced winter hardiness and has been the most frequent cause of widespread winter injury to alfalfa and mixed forage stands in past years. Now is the time to check alfalfa stands and begin planning for harvest or reseeding. Three kinds of winter injury and winterkill can occur in Iowa. Ice sheeting can kill localized areas of alfalfa fields. Plants killed by long-term ice cover or in depressional areas in fields that collect and retain frozen snow melt will not green up and the taproots and crown will begin to deteriorate.
