What Does Bat Guano Mean?

Bat guano is the fecal matter and urine of bats. It collects beneath their roosting places naturally. It has also been used as a fertilizer for a very long time, and can provide essential nutrients and minerals for growing plants.

Bat guano is most often found in caves on the windward side of bodies of water. It needs to be aged for extended periods of time before it can be used by growers.

Given the effort it takes to mine the material, guano can be expensive, but it is one of the most potent natural fertilizers in the world. It’s high in many of the most important nutrients for plant health, including phosphorus, nitrogen, and potassium. Bat guano also contains a host of micronutrients that further fuel plant growth.

In addition to bat guano, gardeners may also use seabird guano and seal guano.
