more importantly - how many gallons of yield per acre?

[Recon Dad]

Well, if you can average 50 bushels per acre and you get 5 gallons per acre I get 250 gallons per acre. A million acres and now we're 250MM gallons of fuel.

How many gallons of fuel do you get out of a barrel of oil, anyone?

Currently the average per acre yield of biodiesel is around 40 bushels per acre. Yields have increased a lot over the years but not much in the last decade. They get about a gallon of biodiesel per bushel with current technology. That could change though. Bushels per acre corn yields have improved a lot over the years as have the number of gallons of ethanol plants get from a bushel of corn.

One thing you have to keep in mind though is that after they squeeze all the oil out of those soybeans, they still have a lot of high nutrition feed left over to sell. They get more from an acre of soybeans than just a little fuel.
