The Villages Polo Club has many horses coming and going during polo season. At max capacity they have 70 stalls filled. Paige M. reports that her Sterling compost system has eliminated the cost of manure removal service and fertilizer for the paddocks ... "two birds, one stone". Special features: they added a small irrigation system that hangs from the underside of the roof. The irrigation system is on a timer and helps to regulate the moisture content. They also overbuilt the original Sterling design to allow for tractor storage or overflow.
