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.
