Comparison of harvest and storage of corn stover and perennial grasses

Kevin J. Shinners, Biological Systems Engineering, University of Wisconsin, 460 Henry Mall, Madison, WI 53706

Corn stover and perennial grasses are agronomic crops that are widely mentioned as potential biomass feedstocks.  There are many challenges to economically producing feedstocks from these crops.  This presentation will compare these two types of feedstocks from the standpoint of yield, composition, harvest timing, moisture, harvest equipment, soil contamination, harvesting rate, bulk density, transportation efficiency, storage alternatives, storage losses, and change in chemical composition in storage.  A comparison of the economics of harvest, storage and transportation of these crops will be provided.
