The message
from "ned" contains these words:

There are those who claim that the best tomatoes are those fed on
sheep dip.

I have never heard such a claim..at least, not from anyone who knows
what sheep dip is.

What do you think happens to the contents of all those rural septic
tanks filled with human waste? No, it is not taken to sewerage farms
for 'processing'. It is spread 'neat' on farmland.

Where? In my long experience of rural septic tanks, the contents are
collected by local councils and taken to sewage plants for treatment.
Some sell heat-treated sewage as fertiliser on land-reclamation
projects.
