Bat guano is the accumulated excrement of bats, often found in caves or under roosting sites. It is rich in nutrients, particularly nitrogen, phosphorus, and potassium, making it an excellent natural fertilizer for plants. Farmers and gardeners often use bat guano to enhance soil quality and promote healthy plant growth. In addition to its use in agriculture, bat guano has been mined for its high nutrient content. It is also a source of phosphate, which is important for various industrial applications. However, harvesting bat guano must be done sustainably to protect bat populations and their habitats.
