Guano consists of ammonia, along with uric, phosphoric, oxalic, and carbonic acids, as well as some earth salts and impurities.

Mining guano.
Mining guano.

The ideal type of guano is found in exceptionally dry climates, as rainwater drains the guano of nitrates. Guano is harvested on various islands in the Pacific Ocean (for example the Chincha Islands and Nauru) and in other oceans (for example Juan de Nova Island). These islands have been home to mass seabird colonies for many centuries, and the guano has collected to a depth of many metres. In the 19th century, Peru was famous for its supply of guano. Bat guano is usually mined in caves. One of the major innovators in guano harvesting was Benjamin Drake Van Wissen.

Guano has been harvested over several centuries along the coast of Peru, where islands and rocky shores have been sheltered from humans and predators. The Guanay Cormorant has historically been the most important producer of guano; its guano is richer in nitrogen than guano from other seabirds. Other important guano producing species off the coast of Peru are the Peruvian Pelican and the Peruvian Booby.

Fertilizer

It is estimated that there is only enough phosphorus from current resources to last about 30 years. This is a problem as vast volumes of phosphorus are needed to produce fertilizer, as it is an essential plant macronutrient. Guano is rich in phosphorus and is an effective phosphorus fertilizer. It is a $1.4 billion industry.


Slang Usage

Slang usage of Guano can be traced back to the amateur ("ham") radio culture in New England, USA, during the World War II era. In that context, the slang term "guano" referred to equipment of dubious value or technological currency, i.e., often outdated, broken, or cumbersome equipment. More recently, "guano" has been used in the engineering profession, and particularly in the audio engineering profession. For example, one might say, "That man's studio is overrun with truckloads of obsolete guano." This usage remains predominantly in the New England region but it is known to crop up occasionally in other areas as well.

Guano is in essence the sedimentary conglomerate of dung, carcasses, feathers, eggshells and sand accumulating in areas where seabirds congregate in confined space on small off-shore islands or rocky outcrops that by virtue of their inaccessibility offer shelter from natural predators.
Guano of a very high quality, due to the absence of sand on the platforms, is reaped every 12-18 month after the end of the main summer breeding season, when a layer of approximately 6 sm.
Guano is rich mainly in Nitrogen (14-16%), Phosphorus (9%) and Potassium (3%), and used as a mix with artificial fertilizers in a liquid or solid form.
