Where should you dump your ponies manure?

I own a horse myself. The horse manure should be disposed off and not left in the field/stable. You could bag it up and sell it or give it away to people that have allotments; to put on there plants. If you have a muck heap then pile it up on there. But if you have no-where to put it then flatten it in the ground somewhere on your OWN land or others if they let you!!
