From what ive seen if your above 2.5% base sat K your corn should grow just fine without limitations given you band your phos if its low. Soybeans phos really doesnt matter but 3.5% or above gets you some decent yield stability. Here that lines up with optimal on a soil test. 2.5% would be low or very low.
