Nutrient considerations with corn silage and stover harvest
Harvested cornstalk residue (corn stover) after grain harvest has traditional use as bedding and co-feed for livestock. Interest is increasing with other uses, especially for energy production such as direct burning and cellulosic ethanol. The potential growth for cellulosic ethanol is large as two plants in Iowa are either proposed or in initial construction. If proven feasible and economical, cellulosic ethanol production and concurrent stover demand could increase substantially.
