[Lowering pH]

David,
If you are trying to raise your pH levels then you should back off on
applying compost, peat moss or anything of that nature as these amendments
will produce H+ ions and make the soil more acid.

I would strongly urge you to take a soil sample for testing first, before
applying anything else at this time.  The lime you are adding is it a high
Calcium lime or dolomite?  Dolomite reacts more slowing as well as supplies
Magnesium.  But, does your soil need Magnesium?  A complete soil test will
tell you this.

I offer free soil sample kits.  If you are interested or have questions on
testing, please feel free to send me a private email.
