323,000,000 harvested acres in the U.S. in 2000.
5.5 gallons of crude oil per acre (your cite)
U.S. Oil consumption (2004): 20.73 million bbl/day
42 U.S. gallons / bbl (http://www.spe.org/spe/jsp/basic/0,,1104_1732,00.html)
U.S. Oil Consumption per year: 7556 million bbl
Oil consumed for fertilizer stock per year: 42.3 million bbl (0.5% of the total)
So is the fact that half a percent of total U.S. oil consumption goes
to fertilizer really a good argument for not growing crops for ethanol
production? Or just a red herring?
