Corn for diesel is mostly bunk, diesel made out of rapeseed is about 100 times less costly.
After 200 years of grain surpluses there are still some who say we don't have enough corn foir food. It will be very interesting to see how much corn farmers plant this year. They are known for shooting themselves in the foot by overproducing.
Isn't soybean oil the most produced oil in the US? Is the bulk rate of soybean oil lower than that of diesel? How does rapeseed oil compare cost wise in bulk.
Sorry for the long list of questions... just trying to be informed.
