Are you talking to me or just exercising your

Thank you Essjay001, that one line confirms my suspicions.

Bet that was difficult without pictures

Fear not MB. That arrow was not aimed at you.

Can we get something straight? The manure that goes onto many commercial
crops is human sh*t..
Sewerage treatment works supply it to farmers.


Cow, sheep, horses etc. that eat grass & stuff have very different digestive
systems to ours, so they are less likely to transmit the kind of bugs &
parasites that are bothersome to humans. Having said that , tetanosis was a
much-feared disease among farm workers.

Dogs, and especially pigs, are physiologically & metabolically too close to
us for comfort. If you want to recycle their excreta, the only safe way is
to the same as with the human stuff: put it through a process where there
are so many microorganisms that the end product is an organic substance that
has lost all biological relationship to the starting material (everything's
changed, even the DNA). This is a professional job; sewage sludge is OK, but
don't try to make it yourself unless you're sure you know how. If you want a
totally irrelevant comparison, numerous twits who think they know all about
mushrooms end up in casualty (if not on the slab) every autumn.

As an addendum, if I remember rightly, the only real problem with sewage
sludge is that it tends to concentrate those heavy metals that form part of
industrial life, but which are now becoming better regulated. As a result,
specialists make sure the treatment doesn't significantly increase the -
perfectly normal - natural burden of heavy metals in the soil. The message
for gardeners is that one treatment may be OK, but don't overdo it if you
have a regular free supply from the local farmer.
