← HistoryIn Aztec chinampa agriculture, which consequence arises if the capillary action delivering water to maize roots experiences high evapotranspiration?
A)Increased nitrogen fixation efficiency
B)Salinization risk within the soil✓
C)Enhanced disease resistance of crop
D)Accelerated mineralization rates of humus
💡 Explanation
High evapotranspiration increases upward water movement via capillary action. This concentrates dissolved salts near the surface causing increased rate of Salinization, because water evaporates leaving salts behind. Therefore soil salinity increases, rather than nutrient availability, impacting the chinampa soil.
