Guano
For other uses, see
Guano (disambiguation). Guano (from the
Quechua 'wanu', via
Spanish) is the
droppings of
seabirds,
bats, and seals .It is an effective
fertilizer and
gunpowder ingredient due to its high levels of
phosphorus and
nitrogen and also its lack of odor.
Superphosphate made from guano is used for
aerial topdressing.
Soil that is deficient in organic matter can be made much more productive by addition of this manure.Guano consists of
ammonia, along with
uric,
phosphoric,
oxalic, and
carbonic acids, as well as some earth salts and impurities. The high concentration of
nitrates also made guano an important
strategic commodity. In fact, the
War of the Pacific between the
Peru-
Bolivia alliance and
Chile was primarily based upon Bolivia's attempt to tax Chilean guano harvesters.
