Which outcome resulted when 16th century chinampa farmers near Tenochtitlan densely planted maize year-round without fallow periods?

💡 Explanation

When maize is continuously cultivated without fallow periods, nutrient depletion accelerates because the high nutrient demand of maize combined with the lack of replenishment through natural processes exhausts available resources. Therefore soil nutrient depletion results, rather than nitrogen fixation, blight resistance, or enhanced drainage which require different soil or biological conditions.
