Narrative:

After completing an aerial application of a farm field approximately 10 miles southeast of lrj airport; I was climbing out to the northwest to my typical ferrying altitude of 500 feet AGL to return to lrj. One mile to the northwest of my target location while climbing; at 350 AGL I notice briefly a white object appear in my lower right corner of my windshield. I initially believed it to be a seagull as birds are rarely white this time of year; but when the object reappeared under the right wingtip of my aircraft I noticed it was in fact a white colored quad-copter type uav. I estimate the uav missed my right wingtip by approximately 50 ft horizontal and 20 ft below vertically. I had no time to take any evasive actions prior to noticing and passing the uav. After discovering the object was in fact a uav; I circled the field to observe the uav was in a stationary hover approximately 350 AGL above a farm field. I then observed what I believed to be the operators of the uav inside the cab of a pickup truck; located on a siding adjacent to the field facing to the west. I did not see any operators or observers located outside of the pickup. After 2 orbits of the field the uav; began a descent to the road along the parameter of the field; and the truck drove to intercept it. I then continued my flight direct to lrj with no further incidents.
