Which consequence resulted when early Aztec terrace-farming over-intensified?

💡 Explanation

Increased frequency of irrigation leads to soil saturation and triggers anaerobic decomposition, because the water displaces oxygen. This production raises byproduct concentration; therefore, maize root health decreases rather than benefiting from added water, nutrients depleting by imbalances.
