You can't really change the pH of our soils to neutral for long. It would
be a losing battle. Most of us have some soil above limestone (alkaline)
and water with tap water which comes from the city (pH of 9-10) or even
worse, from a well (pH of 10-11 and hard with carbonates).

organic matter by .04-.08 % !!! The only way to raise organic content is
slowly over time.

We've been adding compost to our garden by the truckload. We've got a pretty
good soil now, but we'll always keep adding compost.
