Within chinampa agriculture, which limit arises if excessive nutrient-rich sediment accumulates on the plots?

💡 Explanation

When sediment overly accumulates, the reduced porosity of the soil decreases infiltration; consequently waterlogging conditions results from sustained damp from capillary action. Therefore, root hypoxia sets limits to chinampa agriculture, rather than salinity/alkalinity which would require arid/leaching environments or different environmental conditions.
