Composting does not fully decompose all degradable organic materials. Because of various conditions, composting depends on the purpose, scale of production, materials, site, and climate. But whether it is for a small farm or a commercial plant, the first consideration in composting is processing the farmyard manure and crop wastes into a safe compost. The composting method should be able to inactivate the weed seeds and animal and plant pathogens. Accordingly, maintaining a ceiling temperature is very important during the process. The starting materials consist of readily degradable, slowly degradable, and resistant components in suitable proportions. For on-farm scale, the procedures designed and the investment required to process composting should be as simple as possible, especially for remote areas.
