Which risk increases when improperly-terraced chinampas used for maize cultivation experience heavy rainfall?

💡 Explanation

When heavy rainfall occurs on improperly terraced chinampas, excessive leaching happens because fertile topsoil and nutrients are washed away due to poor soil stabilization, leading to nutrient depletion. Therefore, the risk of reduced maize yield due to nutrient deficiencies is increased, rather than stalk snapping, sun scald, or infestations, which require different environmental or biological conditions.
