As Upper Midwestern forage growers realize the extent of winterkill damage in their fields, Extension service specialists have put together resources offering advice.
The University of Minnesota devoted a Web page to winter injury damage, called “Alfalfa weather damage and emergency forages – 2013.” The page has advice on stand assessment, replanting forages and small grains, and it answers questions on autotoxicity in alfalfa.
It also offers livestock producers suggestions on short- and long-term inventory needs as well as how to get the most from damaged crops.
Another information-packed item from the U of M: a story called “Maximizing forage in winter injured and killed stands, Spring 2013.”
The University of Wisconsin Extension Cooperative Service, as part of its drought resources, offers a page called Alfalfa Winterkill. It provides information on alternative crops for forage and making a feed inventory. Additional information can be found in the items, “Nitrogen Credits Following Winterkilled Alfalfa,” and “Alfalfa Removal in Spring.”
In northeastern Iowa, updates are offered in Iowa State University’s (ISU) Crop Notes, by Brian Lang, ISU Extension agronomist.
