I have some fields that are very high fert, some that are very low.  Depends on how they were left when I got them and how long ago I got them.  I can get equal yeilds on low and high testing fields.  It seems 'here' that as long as I apply a good dose of fertilizer to feed the next year, we get along just fine, no matter the soil test.  No, I don't have 147 replications to prove that, I don't need them, I see my results in the field and in the yeild maps and numerical analysis when all is said and done.  Fungicide pays here, even if it is a band aid in your eyes.  Completely balanced fertility is very expensive, fungicide is relatively cheap.  Ben

so what do you consider, completely ?    Balanced fertility ?

High P ? or what. 

if I may ask. do you consider High fertility

what are your P and K numbers %base saturation SamsDad

how about Zinc and Boron ppm   from your high and low fertility areas.

As You well understand, soil Biology is what allows Residual soil nutrition to be available to the plant in sufficient amounts.

More than the rate of the  applied Fertilizer.
