Which consequence resulted from the use of chinampa raised-bed agriculture without adequate nutrient replenishment in pre-Columbian central Mexico?

💡 Explanation

When chinampas lacked nutrient replenishment via introduced sediments, soil depletion occurred because continuous cropping extracted essential minerals faster than natural regeneration, reducing soil fertility and crop yields. Therefore diminished yields resulted, not salinity, subsidence or outbreaks which operate via different mechanisms and environmental conditions.
