The pilot stated that he had been on an aerial application flight, spraying fertilizer on local fields. He had applied 18 loads and was returning to pick up his 19th load of fertilizer. During the landing roll on the grass airstrip, 'the aircraft started turning right and ground looped before [he] corrected directional control.' The main landing gear collapsed, the fuel tank ruptured, and a fire erupted, which consumed the airplane.
