Which mechanism maximized crop yield in Aztec chinampa farming in shallow lake environments?

💡 Explanation

In chinampa farming, decomposing aquatic vegetation recycled nutrients, creating a fertile artificial soil that boosted yields, because nitrogen and phosphates are constantly replenished via localized decomposition. Therefore, nutrient cycling maximized yields, rather than pollination, absorption or pest control which are less directly linked to available shallow lake resource management techniques.
