What's Eating America

Corn is one of the plant kingdom's biggest successes. That's not necessarily good for the United States.

And yet, as organic farmers (who don't use synthetic fertilizer) prove every day, the sun still shines, plants and their bacterial associates still fix nitrogen, and farm animals still produce vast quantities of nitrogen in their "waste," so-called. It may take more work, but it's entirely possible to nourish the soil, and ourselves, without dumping so much nitrogen into the environment. The key to reducing our dependence on synthetic nitrogen is to build a more diversified agriculture—rotating crops and using animals to recycle nutrients on farms—and give up our vast, nitrogen-guzzling monocultures of corn. Especially as the price of fossil fuels climbs, even the world's most industrialized farmers will need to take a second look at how nature, and those who imitate her, go about creating fertility without diminishing our world.
