"Composting is a naturally occurring process that farmers have used for centuries. Under the right conditions, microorganisms grow and multiply, converting the original organic material into a more stable, usable product. Organic materials suitable for composting include leaves, yard and garden debris, grass or cereal straw, food waste, sewage sludge, and livestock manure. With proper control, composting can produce the same products as would occur naturally, but much more quickly. Livestock producers constantly face the challenge of managing manure and meeting environmental regulations. Composting is a possible alternative for handling manure. The benefits include reduced volume, enhanced soil fertility and texture, and reduced environmental risk."--OSU Extension Service.
