Did seabird poop fuel rise of Chincha in Peru?
Archaeologists discover the bizarre fertilizer that powered a pre-Inca empire's rise...
Deep Dive
A new study reveals the Chincha Kingdom's wealth (circa 1000-1400 CE) was built on seabird guano fertilizer. Analysis of 35 ancient maize samples shows elevated nitrogen levels, proving guano from nearby islands dramatically boosted corn yields. This agricultural surplus fueled trade, population growth, and political influence, enabling a strategic alliance with the Inca Empire. The research, published in PLoS ONE, solves a long-standing mystery about the kingdom's economic foundation.
