Jack - can you find a local source of good compost? Someone who can tell
you what's in it, whether or not it got done thermally, maybe even tested
it? If there is manure in the compost, it should have been
thermophyllically composted, achieved 131dF for at least 3 days, and long=
er
(10-15 days) with temps up to 160dF is better.
There's a nefarious category of "compost" NOP has been pushing called
"processed manure materials" - factory feedlot manures that have been coo=
ked
at 150dF for an hour and dried to 12%. Processes like this have been use=
d
to make so-called composts for a long time, and I think this is the kind =
of
stuff you'll get from mass merchandisers - NOT real compost, not good for
teas, but potentially useful as mulch. The cooking/drying routine basica=
lly
destroys the microbiology, but healthy soil, or mixing with good compost =
as
Ted suggests, can eventually re-populate it with beneficials.
The potential problem I keep coming back to on this stuff, though, is
wondering what happens to the synthetics - antibiotics, steroids, hormone=
s,
etc, used regularly in feedlots? (Isn't this just another "dilution
solution?") And is 150dF for an hour enough to destroy pathogens? Even w=
ith
drying, sure seems to me there's still a pathogen re-growth risk there.
