I still don't understand why you are asking about fertilizer if your soil samples came back that you didn't need any. If you want to maintain the current levels then see what each crop or mix you are putting in will uptake and then you can put that down. But I would just top dress the plots later if that is a concern.

You have already stated that your fields are acidic, so adding more of N,P, and K will likely result in it just getting locked up anyway. Seems like a waste of money.
