As a matter of fact, horse manure burns very nicely. (It doesn't burn with a flame, but smolders). Closest smell I can think of is burning cork. What you wind up with is an ash that is an incredible fertilizer for pine trees. Might take a month, but is effective, but you might be admitting that there was a problem.
If you were there first, ask the Judge for 'Costs', and add more to the pile for stress and relief.
Light it up. If that doesn't work, build an airport to accommodate a Wing of B-52 bombers on Yellow Alert at all times. At my place a gun range quieted down the Hood Rats. A 50-BMG being sighted in weekly generates a lot of respect. We do not have a Noise Ordinance, just noise ordnance.
