We composted large quantities of hay and manure for years without issue. We got out of the cattle business and our compost efforts have suffered. We truck in 24x40 trailer loads of leaves mix with old hay and what chicken manure the chickens produce. The piles just don't cook down near as fast as they used to. When we added cow manure to our piles in the past I could cook down 2 trailer loads in about 3 months. We stayed in constant supply. Now we have a tough time doing 2 a year. We turn it with the skid steer regulary. This winter it diddnt always steam. In the past it would keep you warm in the loader.
Do we need more manure or can we get away. With spreading nitrogen based fertilizer on the piles?
