The part 137 aerial application airplane sustained substantial damage while landing on a private grass airstrip. The pilot reported he was landing to the south with the wind from the southeast. He stated the landing strip was "sheltered" from the left crosswind by corn crop on both sides of the strip. The pilot stated he overcorrected for the crosswind and bounced the landing. The airplane drifted left and the left wing impacted the corn. The pilot reported that the resulting drag on the left wing caused a "ground looping effect."
