I'm no expert, but when we had one of our ponds redug by the owner of a excavating firm who got me subscribed to Pond Boss, he chose to have his crews place the muck in 2 locations on our pastures. The 2 plots are about 25 x 25 yards apiece and what they dug out w/ track hoe and dozer ended up about 4 feet thick and we stopped them at the 1/2 acre point for the pond. He advised me to let it sit for a year or two to let it dry before attempting to spread it. The only way that I think it could be spread efficiently is w/ a dozer. I plan to have it tested through the county extension office before we do spread it. It seems maybe overly fertile.

We also compost horse manure and it does have a similar consistency after the manure has composted for a few years, but I think it would take us forever to spread it with a spreader.
