This image illustrates manure composted in an actively aerated windrow, a long, narrow, peaked row. A pipe with vent holes along its length is positioned at the bottom of the row. After the internal temperature rises to 130 to 170 degrees F for at least 72 hours, air is forced through the pipe with a fan or leaf blower. Contrary to what is shown in this image, to avoid environmental contaminations, windrows should be on an impermeable base such as a concrete, covered to prevent seepage from excessive rain, and located away from water sources and low-lying ground. A grassy buffer zone around the compost helps contain unexpected run off. To optimize composting, the compost should have about 50% moisture.
