Which outcome arises when pre-Columbian chinampa agriculture experiences prolonged water salinity intrusion?

💡 Explanation

When saline water intrudes, osmotic stress occurs, because high salt concentrations in the soil reduce water availability for plant roots, inhibiting nutrient uptake and overall growth. Therefore decreased maize yield results, rather than increased fertility, enhanced nitrogen fixation, or reduced pest infestation which depend on different environmental conditions.
