The pilot reported the airplane was loaded with 405 gallons of chemical and both wings were 3/4 full of Jet A fuel. He reported that during takeoff roll the right wingtip and right spray boom "caught the soybeans at the end of the runway." The airplane veered to the right and skidded sideways. He reported extensive damage to the wings, engine, and propeller. He reported there was no mechanical malfunction of the airplane prior to the accident.
