Bat Guano makes an excellent fertilizer and soil conditioner. It’s fast-acting, has little odor, and can be worked into the soil prior to planting or during active growth. 

The higher nitrogen levels are responsible for fast, green growth. Phosphorus aids with root and flower development while potassium provides for the plant’s overall health.  

The Guano is harvested in the USA with the up-most care to ensure that no harm is done by protecting the cave's ecology and only harvesting when the bats have migrated South for the winter.
