Dad would not plant corn before May 9th, and I saw him replant the low spots more than once.
Now the experts say you lose yield potential here if you plant later than May 5th.....
I realize there have been advances in seed and seed coatings, but myself I don't get too worried about it. Every year is different.
One year I stopped planting corn June 6th, certainly there was yield loss on that but it was a tremendously wet year, only got 3/4 of the acres planted I wanted.
I agree with you. It is neat to see what is normal or common in other areas, different soil types. Really makes these forum interesting, and person has to remember my own back yard is not how the whole world works. ;)
