Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Guano is the accumulated excrement of seabirds or bats. Guano is a highly effective fertiliser due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials.
