← HistoryWhich outcome commonly reduced potential chinampa yield during Aztec periods?
A)Accumulation of excessive soil salinity✓
B)Introduction of invasive plant species
C)Depletion of crucial soil nutrients
D)Increased predation by invertebrate pests
💡 Explanation
The *capillary action* mechanism drew subsurface water upward, depositing salts as water evaporated; this induced salinity prohibited optimal crop growth, because Aztec techniques to leach salts were limited, therefore the yield was decreased rather than increased by fertilization.
