What is happening to your nitrogen?

Wetness and late planting lead to concerns about the fate of the nitrogen you applied.  Fabian Fernandez goes through a lot of information in this Bulletin concerning nitrogen levels.  Bottom line is that in the end he says to test.  That is a change.  He technique seems sort of random to me, but  if you are worried about it, you should have some testing done. Keep in mind that low ground will tend to be different than high ground. Fall applied nitrogen is always suspect in a wet year.
