In 'Green Wheat' Drive, Wal-Mart May Transform Farming

Wal-Mart Stores Inc has long used its commercial might to forge a global supply chain with ruthless efficiency. It now has a new target: U.S. wheat fields.

As part of efforts to reduce its carbon footprint and burnish its image as an environmentally responsible company, the huge retailer is sending senior employees into the fields for the first time ever, looking for ways to help farmers reduce their use of carbon-intensive fertilizer or improve logistics.

"We don't have a lot of visibility in the supply chain, so we started in the field," says Robert Kaplan, a sustainability manager at the Bentonville, Arkansas-based firm. "I hadn't seen a wheat field before and I wanted to find out how we go from a green crop in the fields to flour on our shelves."

This May, Kaplan and a colleague were the first Wal-Mart employees ever to attend the annual crop tour across the No. 1 winter wheat state Kansas, a rite of passage for traders, analysts, academics and buyers for the past 55 years.
