At Hummel’s Nissan in Des Moines, Kevin Caldwell sells the all-electric Leaf. Driving one is basically the same as driving a typical gasoline or gas-electric hybrid car, he said, except for a few new features like the semi-autonomous hands-free option. And the fact that you plug it in rather than pumping gas into it.

About a quarter to a third of Caldwell’s Leaf customers are farmers, some of whom grow corn for ethanol.

The U.S. might be on the verge of a boom in new fertilizer plants, which could be good news for farmers, but not the environment.  Today's farmers can produce more from their land than ever before thanks, in part, to nitrogen fertilizer, a key ingredient that has never been more widely available.
