Not sure what you mean Elph. Farmers farm the same way they do for feed corn or the bio fuel. And yes I know this for a fact. The only difference is the type of corn they grow, which is better for the end product one way or the other.

Also corn fuel takes more energy to make then it will give,I risk my life saying this where I live, and will in the end be given up. The farmers love it due to the fact that corn prices have gone up. They havent seen a increase in decades till biofuel hit.
