[G-Man 1]

Ethanol: pie in the sky. Can't last. They are raping the soil.The soil can't be so intensely cultivated for very many years with out destroying the minerals in it. Fertilizer will not bring it back.

[Mr. Lucky]

The intensity of tillage has historically decreased with the increase in corn yields. Put another way, I get about four times the yield off my best corn field than my grandfather did when he was my age, but the soil is disturbed only about a quarter as much.
