I imagine there were some difference between he two field. Different crop maturities, soil compositions, waterlogging. Given that many areas within the damaged field are undamged, then if it were due to wind, then the difference between the two fields could still be pretty marginal.
There's the obvious color difference in your first photo, just much less apparent here.
The point is there are hundreds of possible explanation, without going to the practically imposible one of wind that only affects one field. A difference in the fields is simply the most plausible explanation.
