I'm assuming it has to be composted because the worms will turn their noses
up at it otherwise. Is that correct?



The worms will like horse manure any old way. The problem with not
composting it is that, unlike cows, that digest their food fairly
completely, horses are just large shredders and the stuff goes through
only minimally changed. It therefore contains lots of weed seeds, which
the composting process will kill (if it is done properly).
