Bat guano, or dung, has a long history of use as a soil enricher. It is obtained from only fruit and insect-feeding species of bats. Bat guano makes an excellent fertilizer; it’s fast-acting, has little odor, and can be worked into the soil prior to planting or during active growth.

What Do They Use Bat Guano For?

There are several uses for bat guano. It can be used as a soil conditioner, enriching the soil and improving drainage and texture, and a suitable fertilizer for plants and lawns, making them healthy and green. It can be used as a natural fungicide and controls nematodes in the soil as well. In addition, bat guano makes an acceptable compost activator, speeding up the decomposition process. With so many uses, why would you not use bat guano?!

How to Use Bat Guano as a Fertilizer

As a fertilizer, bat guano can be used as top dressing or worked into the soil and can be use fresh or dried. Typically, this fertilizer is applied in smaller quantities than other types of manure.

Bat guano provides a high concentration of nutrients to plants and the surrounding soil. According to the NPK of bat guano, its concentration ingredients are 10-3-1. This NPK fertilizer analysis translates to 10 percent nitrogen (N), 3 percent phosphorus (P), and 1 percent potassium or potash (K). 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.

Note: You may also find bat guano with higher phosphorus ratios, such as 3-10-1. Why? Some types are processed this way. It’s also believed that the diet of some bat species may have an effect. For example, those feeding strictly on insects produce higher nitrogen content, whereas fruit-eating bats result in a high phosphorus guano.
