The Indore Method:
Sir Albert Howard created this method as way of “assuring that proper amounts of different materials get incorporated into the heap (Rodale 1973, p.47).” The focus is on proportions of the ingredients: 3-4:1 organic plant matter to manure plus a small amount of rock material (limestone or chalk).
The primary process of the Indore method is to layer these materials alternately, to ensure decomposition of the heap, and to allow it to take place on its own, with little involvement or labor necessary. The layers provide the proper amount of aeration necessary for nitrogen-rich manure to break down the carbon-rich plant materials without needing to be constantly turned.
The base of the heap is straw or brush and they layers are as follows: six inches of green plant matter, 2 inches of manure, and a thin layer of rock or earth. The suggested height of the pile is 5 feet. Shredding materials before adding them to the pile creates a better form for insulation and air and moisture retention.
The materials should be turned and mixed up for the first time six weeks after the pile is created, and once more after 12 weeks. Because of its low maintenance, this method is best known for its value to large scale composting, such as needed for a farm or large garden.
The Indore compost heap is a great place for earthworms, who speed up the process quite a bit.
