Guano is the accumulated excrement of seabirds and bats. As a manure, guano is a highly effective fertilizer due to its exceptionally high content of nitrogenphosphate, and potassium, all key nutrients essential for plant growth. Bird guano has high levels of nutrients like nitrate and ammonium. By mass, it is 8–21% nitrogen; the nitrogen content is about 80% uric acid, 10% protein, 7% ammonia, and 0.5% nitrate. Some of bird guano’s most common chemical elements are phosphoruscalcium, and magnesium. It may react with the rocky substrate of islands like basalt to form authigenic, phosphatic minerals including taranakite and leucophosphite. When freshly excreted, the guano of insectivorous bats consists of fine particles of insect exoskeleton, which are largely composed of chitin. Elements found in large concentrations include carbonnitrogensulfur, and phosphorus.
