Corn stover has potential as a bioenergy feedstock in North America. We simulated production
costs for stover harvest (three-pass and two-pass with baling or chopping, and
single-pass with baling or chopping) and on-farm storage (outdoor and indoor bales, outdoor
wrapped bales, and chopped stover in bags, bunks, or piles). For three- and two-pass
harvest, chopping was 33e45% more expensive than baling. For baling and chopping, twopass
harvest was 25% cheaper than three-pass. Single-pass chopping harvests were on
average 42% cheaper than three-pass or two-pass chopping. Single-pass baling was
cheaper (4e31%) than multi-pass baling at low rates of stover collection, but more
expensive (1e39%) at high rates of collection. For bales,
