Planting a winter rye cover crop after corn silage is an easily implementable conservation practice. Harvest as forage the following spring can generate income which should make the practice even more appealing for producers. Forage best management practices can be found in an NPM Program publication: Planting Winter Rye after Corn Silage, Managing for Forage (http://ipcm.wisc.edu/Publications/tabid/54/Default.aspx). Managing rye for optimum forage yield and quality will maximize conservation benefits including nutrient management. In this paper we will discuss nutrient management implications and opportunities.
