印加前钦查人利用海鸟瓜诺在800年前给玉米施肥,促进农业,促进其王国的崛起。 Pre-Inca Chincha people used seabird guano to fertilize maize 800 years ago, boosting agriculture and enabling their kingdom's rise.

2026年2月11日在SPLOS One发表的一份新研究报告显示,秘鲁南部的Inca Chincha前人民至少800年前将海鸟guano用作玉米肥料,提高干旱沿海地区的农业生产力。 A new study published in PLOS One on February 11, 2026, reveals that the pre-Inca Chincha people in southern Peru used seabird guano as fertilizer for maize at least 800 years ago, boosting agricultural productivity in the arid coastal region. 对古代玉米鳕子的分析表明氮同位素含量异常高,证实了支持人口增长、复杂社会和政治权力的瓜诺广泛使用。 Analysis of ancient maize cobs showed unusually high nitrogen isotope levels, confirming widespread guano use that supported population growth, complex society, and political power. 调查结果显示,早在欧洲接触之前,以guano为燃料的农耕是钦查王国从1000到1400的中部。 The findings suggest guano-fueled farming was central to the Chincha Kingdom’s rise from 1000 to 1400 CE, long before European contact.
