This presentation will help consultants, growers, and other practitioners in the Corn Belt as they consider the advisability of harvesting corn stalk residue after grain harvest for use as biofuel. Basic information about residue is presented, along with results of a study on the effects of residue removal, tillage, and nitrogen on continuous corn grain yields. We will consider how other management factors might need to change if residue is removed, and will discuss the effects of removal on sustainability of the continuous corn system.
