New archaeological research, led by Dr. Jacob Bongers, reveals that seabird guano fertilization was a cornerstone of the Chincha Kingdom's economic and political power in ancient Peru. By examining maize samples from burial tombs in the Chincha Valley, scientists found unusually high nitrogen levels, indicating intensive use of guano from the Peru===Chincha Islands. This agricultural surplus of maize fueled the Chincha Kingdom's wealth, trade networks, and population growth, enabling them to become prominent maritime traders. The study suggests that guano, rather than prestige goods, was central to their regional standing and influenced diplomatic arrangements with the highland Inca Empire, which relied on the Chincha Kingdom for maize. The findings highlight how the Chincha Kingdom's mastery of a complex ecological system, connecting marine and terrestrial environments, generated agricultural abundance and political capital.
