Which factor primarily limited the potential productivity of chinampa agriculture for the Aztecs upon seasonal flooding?

💡 Explanation

When seasonal flooding occurred, waterlogging in the chinampas promoted anaerobic conditions because oxygen diffusion was severely restricted in saturated soils, leading to rapid denitrification and nutrient loss. Therefore nutrient depletion limits productivity, rather than insufficient sunlight, loss of seed banks, or salt accumulation which require other conditions.
