Which primary mechanism enabled the intensive floating garden 'chinampa' agriculture of the Aztec civilization?

💡 Explanation

Chinampas used nutrient recycling because decomposing vegetation and mud were continuously added to the raised beds, continually replenishing nutrients to ensure soil fertility and enable sustained intensive agriculture. Therefore nutrient recycling is primary mechanism, rather than windbreaks, crop rotation, or aqueducts directly supplying nutrient availability.
