Which crop yield improvement occurred with the introduction of chinampa agriculture?

💡 Explanation

With layered soil construction, chinampas absorb solar energy, warming quickly due to elevated artificial islands built within shallow lakebeds, extending the growing season because of the localized warmth and enhanced frost protection. Therefore chinampas extended the growing season, rather than reducing nitrogen needs, resisting erosion, or decreasing pest susceptibility which rely on modified crop genetics or land structure.
