Modern agriculture has little to do with the free market.

Agriculture gets a whole bunch of subsidies and tax breaks for sure.

The USDA notes steady increase in fossil fuel input in ethanol corn production since 1991. They also note steady increase in fertilizer. They do note that the BTU per pound has dropped some since 1991. (About 20% down the page is the chart)
