Farms are growing, but jobs aren't

The property Kevin Liefer and his son, Kirk, cultivate in Southern Illinois has been expanding for decades without adding a single manager. These are boom times for farming and a bust for farm jobs.

The 3,600 acres of mostly corn, wheat and soybeans the Liefers hold were about 30 separate, individually operated farms more than 40 years ago, said Kevin. As families left, the homesteads near Red Bud, about 40 miles southeast of St. Louis, melded into one operation.

Older tractors were replaced with models that cultivate more ground and serve as miniature offices, complete with global positioning systems that allow them to steer themselves. Mobile phones enable communication while in the fields.
