Joe and Kim O. chose to construct an aerated O2Compost Benchmark System to resolve two needs: a way to contain and more quickly compost the manure from their six horses on fine, dust-free bagged shavings. The finished compost is spread back on the pastures. "We really like the system, it is very effective. It also looks nice. The only place we had available for the compost was highly visible, so this was a great solution."
