← HistoryWhich outcome arises when pre-Columbian chinampa cultivators neglect the 'xochimolli' maintenance?
A)Accelerated nitrogen fixation process occurs
B)Increased agricultural land biodiversity blooms
C)Elevated risk of alkaline soil buildup
D)Decreased soil aeration; root asphyxiation✓
💡 Explanation
Neglecting 'xochimolli' degrades soil structure because it reduces organic matter, therefore the mechanism of compaction occurs; this causes waterlogging rather than enhanced nutrient cycles since the soil loses crucial pore spaces.
