Yes, that will do it...

Have you given consideration to raising the OM as a pH buffer?

It has been discovered that the root tips themselves change the pH in the immediate vicinity of where it is drawing from, so as to survive in otherwise hostile pH soils...

I confess I really haven't had a real discussion about this subject and am not sure if any of this is true... I do know that compost increases vigor every time I use it, but I only have personal assumptions as to why...
