A study from Scotland about the production of corn is more than a little suspect. What type of nitrogen is the professor applying? By what method? What is the alternative ground cover? (In the US, far more nitrogen is applied per acre, and in a far more inefficient manner, to suburban yards than to the corn fields they replaced)
at the present time,
the cost of E85, does not make sense.
commodity ethanol , is 1.56 a gallon.
there is a 50 cent subsidy.
the subsidy should cover the motorfuel tax.
Because of transportation problems, and lack
of competition, the markup is out of line.
I expect that to gradually improve.
