The problem started long before the cold arrived, according toKAAL-TV,a Minnesota news station. Last year's drought weakened the plants, making them more susceptible to winter’s killing freeze.

Lisa Behnkin, a regional extension educator at the University of Minnesota Extension, told the news station that it has put farmers in a dire situation.

Farmers in the area normally are able to harvest three or four cuts of alfalfa during summer, but this year they have to replant and will be lucky to get one or two cuts. To met their needs, they have to seek out the forage from other states.
