This ASP compost system uses a 4-pipe system to process the manure and bedding produced in one month from 40 horses on wood pellet bedding. While one pile is "cooking", an adjoining pile is being constructed and at the end of the month the blower is simply moved over and the process is repeated. The finished compost is sold to the neighboring vineyards for use as a top dressing/mulch for weed control and to provide both macro- and micro- nutrients.
