Farmers may get cash for unused corn cobs

Rather than plowing corn cobs under, Iowa farmers will be able to sell them to plants that will turn them into ethanol and fertilizer.

The farmers can just leave the cobs piled in the fields and have them picked up. 25,000 acres of corn fields will be used, generating about a ton of cobs per acre, which the farmers will sell for $30-60 per ton.
