Harvesting corn stover as a biomass feedstock is a growing practice within the Midwest US. Corn stover harvesting generally occurs soon after corn grain harvest is complete and ahead of fall tillage or fertilization. Corn stover is generally baled to create high density packages that can be transported efficiently. Both round bales and square bales can be formed depending on the end use. Round bales are generally more suitable for lower volume uses like animal bedding while large square bales are preferred for industrial uses like cellulosic biofuels.
