This is a 3' high pile of composting horse manure.  Ideally, the water content should be about 50%, and the compost should in narrow rows to facilitate turning when the internal temperature reaches 130 to 170 degrees F for at least 72 hours.  Higher temperatures or longer periods of high temperature can terminate the desired microbial action. By contrast with this example, the compost area should be roofed and located on an impermeable base such as concrete to minimize chances of environmental contamination. A grassy buffer zone around the compost area provides added protection.  Locate the compost down wind from nearby residences.
