← HistoryWhich outcome resulted from the Aztec civilization's practice of continuously dredging canal mud onto chinampa plots?
A)Increased soil salinity on crop lands
B)Decreased soil fertility over time
C)Sustained high crop yields annually✓
D)Waterborne disease spread increased dramatically
💡 Explanation
When canal mud was dredged, nutrient replenishment occurred because the mud contained organic matter and minerals, leading to enhanced chinampa soil fertility for agriculture. Therefore consistent high crop yields were sustained, rather than salinity increase, decreased fertility, or disease outbreak which require different environmental or biological processes.
