SIT in the seat of a tractor cab that's set up with autosteer, and you'll find yourself riding the next wave of Midwestern ag technology.

They plant orchards for clients with GPS, giving each tree an address on its own 2-foot-by-2-foot space. The next step in their industry is to send the tractor out at night with instructions to spray just a few particular trees.
