A university extension website would tend to be an authoritative, respected source of information. The Sanpete Cooperative Extension in Ephraim, Utah, links 60,000 cubic yards of turkey litter with 24,700 tons. That would be about 2.43 [2.429121] yards.
there is about 1.25 yards to a ton,so 22.5 tons would be approx 18 yards
