Cultivating a Crop of Hope

When it grows high and thick in midsummer, the crop that might fill Virginia's gas tanks, revitalize its farm belt and keep its mud and manure out of the Chesapeake Bay looks like . . . weeds. Like the world's most overgrown lawn.

At a Virginia Tech agricultural research center here, in this small town west of Fredericksburg, the switchgrass plot is an unruly, waving thicket of seven-foot-tall green stalks. But it only looks neglected: This is one of the center's most prized plants, a formerly obscure prairie grass now projected to be a major source of farm-grown fuel.

"That'd be some energy, right there," said Dave Starner, the center's superintendent, holding a freshly cut bundle of it.

Researchers across the country think that switchgrass could help supplant corn as a source for the fast-growing ethanol industry. In Virginia, some officials are trying to make the state the Iowa of the new cash crop. They're urging farmers to grow it and envision dozens of refineries that will turn the stalks into fuel.
