Researchers Working on System for Harvesting Corn Stover

A research team at Iowa State University is designing systems for simultaneous harvesting of grain and stover (the stalks, cobs and leaves) during corn harvesting, with the goal of providing the raw materials for cellulosic ethanol processing.

The researchers are developing stover attachments that can be used on standard combines. The result would be an additional cost to farmers of about $10,000 to $15,000 instead of the six figures it would take for a separate combine to harvest stover. The attachments would also allow farmers to harvest grain and stover with one pass through a field.

Although tests of the prototype machine have been successful, the researchers acknowledge that there is still much work to be done in terms of stover harvest capacity, transportation, storage, and soil composition.
