Interpretive Summary:

Technical Abstract: Corn stover has been identified as an important initial source of biomass for conversion to ethanol and other biofuels. This poster presentation outlines on-going cooperative research being conducted near Ames, IA. Our university partner is responsible for developing the one-pass harvester and our INL partner for determining feedstock quality for conversion to ethanol. This study has shown that harvesting the cob and stover from the upper 50% of the corn plant would provide a high-quality bio-energy feedstock and some soil residue cover at a reasonable harvest speed. Harvesting lower stalk portions increases pre-treatment cost, nutrient replacement cost, and results in very little soil cover.
