Sure. The first link is the first one that popped up when I did a search for biodiesel and "blenders credit" on Google. You could find plenty of others that will say they same thinh. The blenders credit is one dollar per gallon.

Next I did a Google search for 'biodiesel yield soybeans ' and the first link that popped up says they get 48 gallons of vegitable oil per acre of soybeans. Note that the yield of biodiesel per acre is going to be slightly less than the yield of vegetable oil. The next link is to the Wikapedia entry for biodiesel. They say you can get forty gallons of biodiesel per average from soybeans. I've reports that show the national average as being slightly higher than that but I don't have time to do a lot of research today to find more reliable sources. If you don't like my links though you can do your own search and I'm sure you will find that I am right.

Well done, and without personal insults, unlike Keith & Concho instantly resort to, for WHATEVER reason. This is how debate is supposed to work.
