Manure is
organic matter, mostly derived from animal
feces except in the case of
green manure, which can be used as
organic fertilizer in
agriculture. Manures contribute to the fertility of the
soil by adding
organic matter and nutrients, such as
nitrogen, that are trapped by
bacteria in the soil. Higher organisms then feed on the
fungi and bacteria in a chain of life that comprises the
soil food web. It is also a product obtained after decomposition of organic matter like cow dung which replenishes the soil with essential elements and add humus to the soil.
