    • n guano A fertilizing excrement found on many small islands in the Southern Ocean and on the western coast of Africa, but chiefly on islands lying near the Peruvian coast. The Peruvian guano of commerce formerly came from the Chincha islands; but in recent years the chief sources of supply are Pabellon de Pica, Punta de Lobos, Huanillos, and other places on or near the Peruvian coast. Those islands are the resort of large flocks of sea-birds, and are chiefly composed of their excrement in a decomposed state. Guano sometimes forms beds from 50 to 60 feet in thickness. It is an excellent manure, and since 1841 has been extensively used for that purpose. It contains much ammonium oxalate and urate, with phosphates.
    • n guano A fertilizer made from fishes. See fish-manure.
    • guano To manure with guano.
