Over the years I've experimented a bit with using these (llama, horse, cow,
sheep, etc.) as either teas, amendments, or as the medium itself (on the
latter, see the writings of Nic van Bosch from Tasmania). Quite a bit was
written about using manure teas for orchid nutrition in the set Lindenia,
for example. Some genera (phals, cymbidiums, etc.) seem to like to grow in
pure horse manure. Go figure!
Some time ago Andy mentioned the passing of a generation of fine orchid
growers. While there's never any way to preserve all of their knowledge and
wisdom, I do hope that orchid organizations like the AOS are taking steps to
preserve the writings (especially manuscript writings) of these individuals
as well as doing some "oral history" where they are interviewed and these
records preserved.
