What is the chemical composition of dry cow dung?


Wiki User

Dry cow dung is mainly comprised of organic matter including fibrous material that passed through the cow's digestive system, and dead and live microflora. Exact chemical composition is of mostly carbon, nitrogen, hydrogen, oxygen, phosphorus, etc. with salts, cells sloughed off as the digesta went through the digestive tract, microflora that came up from the rumen, and cellulose, lignin, fibre and hemicellulose. Originally dung was quite moist, but as time goes on the water from the feces evaporated, drying up the patty, leaving it with primarily organic matter similar to the partly decomposed plant matter that is left after each growth cycle.
