Manure
From Conservapedia
Manure is material—usually some kind of farm waste material, often consisting the feces of animals—used as agricultural fertilizer. It must be used with care to prevent the spread of bacterial infection.
Human manure, known as "night soil," was a traditional form of fertilizer in China and Japan. In the United States, heavily treated products derived from municipal sewage are sold for use as fertilizer, one example being Milorganite.[1]
Green manure consists of crops which are deliberately planted for the purpose of being plowed under later in order to improve the soil.
