| If the pH is low, I would think it would be a waste of money. The "experts" say that P only moves about 2 inches per year, depending on pH and conditions. So, I would say it might be a little late for that crop, but not for the subsequent crops. Truth be known, most P surface applications probably most benefit the following crop rather than the one that it is being applied to.
