Corn stover could be used to make bio-oil, soil enricher

Turning corn stover into bio-oil and a soil-boosting product could be more financially and environmentally rewarding than using the harvest residue as feedstock for cellulosic ethanol, scientists from the Agricultural Research Service reported.

Using the same process, about 18% of the corn stover could be converted to bio-char, a soil enricher that can isolate carbon.
