Divert runoff away from stockpile and grazing areas to prevent re-infestation of parasites. If your facility is smaller and you plan to utilize the bin system, select a site large enough to fit the number of bins needed. Two bins or more result in faster and more efficient composting. Completely fill one bin first with manure and stall wastes, then start filling subsequent bins, one bin at a time. If you fill your bins one at a time, materials in previous bins will compost, resulting in a quicker product.
Bins are easy to build.
Ideally, build the size or number of bins to accommodate all the waste materials accumulated for several months of composting. A concrete floor and strong walls are handy for larger bins, and a gravel access is convenient for loading or using a wheel barrel to bring the manure to the heap. For the vertical compost pile, material is added to the top or sides of the mass. While frequent turning or inserting pipes will hasten decomposition, some horse owners build a new pile once or twice a year and only turn the piles a couple of times within a year, letting the pile slowly decompose over a year or so. The windrow pile typically is about five to six feet tall and six to eight feet wide.
