← HistoryWhich benefit directly arose from pre-Columbian chinampa agriculture in the valley of Mexico?
A)Increased nutrient availability via raised beds✓
B)Reduced erosion via terraced hillside planting
C)Enhanced pollination via crop rotation
D)Improved water management via irrigation channels
💡 Explanation
When chinampas were constructed, aquatic plants decomposed within the raised beds, which increased nutrient remineralization by microbial activity within the sediments, leading to enhanced soil fertility. Therefore nutrient availability improved crop yields, rather than erosion control, pollination or water distribution, as these required different construction.
