Etymology

The word 'guano' originates from the Spanish term 'guano', which itself comes from the Quechua word 'wanu', meaning 'dung'. The use of guano as a fertilizer dates back to the pre-Columbian civilizations in South America, particularly among the indigenous Andean people who recognized its value for enhancing agricultural productivity. As European powers expanded their agricultural interests in the early 19th century, they became increasingly aware of the fertilizing properties of guano. This led to significant guano mining operations, especially in Peru and Chile, which were among the richest sources of seabird and bat excrement. The guano trade quickly became a global phenomenon, driving economic growth in those regions. By the mid-19th century, guano was seen as a miraculous agricultural product, prompting nations to compete for control over guano-rich islands in the Pacific Ocean. The unique properties of guano were essential during the agricultural revolution, which improved food production worldwide.
