Which consequence occurred when pre-Columbian chinampa agriculture extended into overly saline lake regions?

💡 Explanation

When chinampas extended into saline regions, osmotic stress increased because high salt concentrations reduce plants' ability to absorb water efficiently, thus hindering maize growth. Therefore reduced yields resulted, rather than increased nitrogen/phosphorus or improved infiltration which need different environmental/chemical conditions.
