RE: Build up of fertilizer requirement
the general rules of thumb in the Illinois Agronomy Handbook are 9 lbs of P2O5 and 4 lbs of K2O to increase soil test levels by 1 lb per acre.
At 46% P2O5 for DAP, 19.6 lbs of DAP will supply 9 lbs of P2O5.
At 60% K2O for MOP, 6.7 lbs of MOP will supply 4 lbs of K2O.
What soil types are you working with?
