(NYT26) MARYSVILLE, Calif. -- May 10, 2008 -- AERIAL-SEEDING-4 -- Pilot Danny Hawk taxis his seeding plane, near a rice seed truck, left background, as rice seeds from previous seedings lay on the ground, in a field in Marysville, Northern California, May 2, 2008. Hawk is one of dozens of agricultural aviators in California, which plants more than 90 percent of its rice fields from the air, a method that dates to the 1920s but has gone high-tech over the last decade with the introduction of global positioning systems that allow pilots to drop seed to within three feet of a target.
