Heidi Johnson, Crops & Soils Agent at Dane County UW-Extension, hosted the “Cover Crops and Manure Management after Corn Silage” field day in Waunakee, Wisconsin on October 24th. PARM learned about the various benefits of multi-species cover crops, and what species of cover crops Wisconsin farmers are getting the most benefit from. Johnson mentioned small grain cover crops as superior to legumes and brassicas when following corn silage, as small grains increase infiltration and greatly reduce erosion. Another lesson learned was Wisconsin farmers’ rejection of cereal rye based on problems with spring killing. Spring barley is a better choice for Wisconsin farmers, states Johnson, because the crop establishes well and is better at winter-killing.
