Kudo's for bringing this up as a topic.

I don't know if a digester will neutralize the herbicide clopyralid, but this could be a downstream concern for using the sludge. I think most farmers are aware of the problems with clopyralid but if used by unscrupulous hay suppliers would give a the sludge a bad name. Clopyralid has been found to pass through a cow and remain active in the resulting compost.

Thanks for pointing this out - I'll pass it on to the farmers I know. If I can find out any more information I'll get back to you.
