Which environmental consequence occurred in pre-Columbian Mesoamerica when intense terrace farming of maize exceeded capacity?

💡 Explanation

When intense terrace farming exceeded environmental capacity, soil nutrient depletion accelerated because continuous maize crops extracted nitrogen, phosphorus, and potassium faster than natural replenishment, severely impacting yields. Therefore nutrient depletion resulted, rather than salinization, methane increase or deforestation decrease which correspond to unrelated alternative farming practices.
