Guano Definition from Encyclopedia Dictionaries & Glossaries
Guano (via Spanish, ultimately from the Quechua wanu, meaning 'dung') is the excrement (feces and urine) of seabirds, cave dwelling bats, and seals. Guano manure is an effective fertilizer due to its high levels of phosphorus and nitrogen and also its lack of odor. It was an important source of nitrates for gunpowder. Soil that is deficient in organic matter can be made more productive by addition of this manure.
