I think that this is an excellent question. I am a firm believer that organic
farming must limit inputs from organic farms only. There is a vast difference
between manure sourced from conventionally versus organically raised animals.
Furthermore, I don't think that composting eliminates all of the problems. One
problem you did not list is the issue of pathogens in animal fecal material.
Contaminated manure combined with no or improper composting is the prime
reason why we are seeing pathogens spreading to non-animal products (ie.
fruits and vegies). And no, I don't endorse the ag business rationale that it
is the wild animals that roam in the fields that are the only source of
contamination.
Thanks for raising this issue.
