I think last year's yields will match or better this year in my heavy ground in central IL. I think like you, that get up in the air or climb a leg and see the holes and light yellow corn without any N. The beans that were under water are a foot or so shorter than the others and you know the higher ground will not make up the difference.
When the general economy gets better like it is starting, our party is over. We will be back handling money. If we have an early fall, the drying bill will take a bunch.
