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.
Materials are added at the end of the pile, hence the pile can grow to any length.
Generally, these piles are turned with front-end loaders or specially equipped tractors. Hauling In situations where there is limited time or space, horse owners might transport the manure off the premises. Burning Where zoning regulations permit, burning manure can be a fast and efficient method. Allow the manure to dry by spreading it out. When dried, gather the pile in an open, bare area away from pasture, dry grass, and buildings, and where the smoke and smell won't offend neighbors.
