Here is a copy of a pH chart that is essentialy the same with 3 pH
meters that I own

According this chart
as soil becomes more acidic, nutrient absorbtion drops
Below a pH of 6.5 P.
Below pH 7.0 Magnesium and calcium starts to drop.
As soil become more alkaline
Above pH 6.0 Iron drops
above pH 6.5 Maganese drops.
A sort of average of the 5 elements keeping the soil between 6.5 and
7.0 will yeild maximum absorpstion of all needed elements.
