Narrative:

I departed on an IFR flight plan with the intention of canceling my IFR flight plan and picking up VFR flight following and diverting to my destination; a private strip; which I did. I cancelled VFR flight following when I started my descent for the strip. VFR conditions were present at both the departure airport and the destination.upon arrival at the airstrip I flared and touched down. At this point a gust of wind hit me and pushed the plane back into the air. The plane then came back down; touched down firmly and 'porpoise' back into the air. It came down firmly a second time and I then 'held the airplane up' and let it settle back to the landing strip. At this point the wind had pushed me to the right side of the airstrip. The right main landing gear went off the airstrip into the adjacent grain field which had recently been plowed. At this point the soft dirt of the grain field 'sucked' or pulled me farther to the right of the airstrip into the grain field. We proceeded for approximately 150 feet in the grain field where the nose wheel finally 'dug in' and the airplane nosed over striking the left wingtip first then coming to rest on its top. My third class medical is current as well as the airworthiness and weight and balance for the airplane. As far as I am aware I was in no violation and was operating within the limits of the aircraft.
