Which agricultural vulnerability emerges if an ancient chinampa soil barrier fails?

💡 Explanation

Nutrient leaching overwhelms root aeration because the mechanism preventing nutrient loss through the barrier's degradation is compromised. Therefore, nitrogen compounds no longer foster plant growth rather than excessive cooling or seed burial from upland activity after inundation.
