Tough, cold Wisconsin winters translate into fewer cover crop species requiring spring termination before planting. For a quick chart of cover crop species that tend to winterkill, download the Cover Crop Termination fact sheet . Here is a short list of the cover crops that will need to be terminated in the spring: winter (cereal) rye, winter barley, winter wheat, winter triticale, red clover, sweet clover, and hairy vetch. There are a few cover crops that may or may not winterkill depending on the severity of winter and degree of snow cover; these include canola, winter pea, and annual ryegrass.
