Healthy soil and sustainable growing

[<pbunch@cox.net>]

Several people on the list have mentioned the use of human waste for 
agricultural purposes. I'm interested in what peoples experience has been 
with this and what kinds of precautions people are taking to break the 
pathogen-human cycles in order to avoid disease transmission. The World 
health Organization has done a lot of work on this and their guidelines are 
available online.

This appears to me to be one of the crucial linkages that will have to be 
established in a steady state economy. Nutrient recycling is a fundamental 
ecosystem function/service which must be integrated in the closed human-earth 
system. Of course pathogens have evolved to exploit this system and we have 
to assure a reasonable level of safety.
