Which long-term benefit resulted from the development of chinampa agriculture by pre-Columbian civilizations in Mesoamerica?

💡 Explanation

Chinampas utilized nutrient cycling because sediment dredged from canals provided a continuous supply of organic matter, enriching the soil and boosting fertility sustaining high yields over extended periods. Therefore enhanced soil fertility was observed, rather than the listed alternatives which result from different agriculture processes with different constraint.
