FARMERS' EYE IN THE SKY

Equipped with a state-of-the-art thermal camera, the drone crisscrossed the field, scanning it for cool, soggy patches where a gopher may have chewed through the buried drip irrigation line and caused a leak. In the drought-prone West, where every drop of water counts, California farmers are in a constant search for ways to efficiently use the increasingly scarce resource. Cannon Michael is putting drone technology to work on his fields at Bowles Farming near Los Banos, 120 miles southeast of San Francisco. About 2,100 companies and individuals have federal permission to fly drones for farming, according to the drone industry's Association for Unmanned Vehicle Systems International. Federal regulators planned to relax the rules Monday on commercial drones, a move that could spur even greater use of such aircraft on farms. Michael is descended from Henry Miller, a renowned cattle rancher, farmer and Western landowner who helped transform semi-arid central California into fertile farmland 150 years ago by building irrigation canals, some still flowing today.
