Which effect was historically achieved by pre-Columbian chinampa agricultural techniques in Mesoamerica's lakebeds?

💡 Explanation

Chinampas utilized nutrient-rich lake sediment and decaying vegetation as fertilizer because cyclical processes replenish soil fertility, achieving higher and more durable maize yields. Therefore increased maize yields resulted, rather than salinity reduction, enhanced pollination, or erosion control, which involve different environmental factors.
