I am heading out to plant about 15 acres of Canola seed. It is supposed to be the seed that biodiesel is made from. 100 lbs is only 2 sacks about the size of 25 lb dog food sacks. I don't know how many lbs of it it takes to make a gallon of biodiesel, but at $3.00/gal, Canola might be worth something next spring.... Cecil in OKla
