Mike,
Here is a quote from a soils lab on my soil test.
"High levels of organic matter should have a beneficial effect on the
growth and "soil" PH may not be as critical."
I would imagine that as the soil digest the OM it will come down.
I think that you should focus on the base saturations of potassium
,magnesium, calcium achieveing a balance of
8%K,15%Mg,85%calcium...........MB
