Guano is used as a valuable nitrogen and phosphorus fertilizer; it contains about 9 percent nitrogen and 13 percent phosphoric acid, potassium, and calcium. Accumulations of guano are found on islands off the coasts of Chile, Peru, and South Africa as well as on the islands of the Caribbean. Guano is also the name given to the artificially prepared (mainly in Japan and Norway) mineral fertilizers from the waste products of the fishing and seal-hunting industries.
