← HistoryOn pre-Columbian chinampas, which outcome resulted from densely planting willow trees along perimeter edges?
A)Increased soil nitrogen fixation
B)Reduced soil salinization rate
C)Enhanced dike structural integrity✓
D)Improved irrigation water acidity
💡 Explanation
When willow trees were planted along chinampa edges, root stabilization occurred because the dense root systems interlocked soil particles, binding the island edges. Therefore enhanced dike structural integrity resulted, rather than nitrogen fixation, reduced salinization, or acidity which involve different chemical interactions.
