Hi Steve,
I tend to agree with Rivka the price per acre may be a bargain but you
probably are better off looking for something more pH neutral. In one of
your emails you said planting 3 acres which isn't very much ground and
you soon would be expanding that. Then you would be trying to control
the pH on more acreage. However the trade-off for the terrain
(outcropping) and wooded area they make it worth your while. Based on
conditions in this area, ground agricultural limestone is something they
apply every few years and to bring up the acidity is something you would
be doing continually. It wouldn't be a one-time treatment.

PS. It's not fun digging in soil with stones.
