Which agricultural benefit resulted when Aztec chinampas used "sunken gardens" methodology in shallow lake Texcoco?

💡 Explanation

When chinampas used "sunken gardens", nutrient cycling increased because aquatic plants and organic matter decomposed, enriching the soil. Therefore enhanced nutrient cycling results, rather than reduced salinity, decreased pest proliferation, or minimized erosion which rely on different environmental modification principles.
