History

Which process most severely reduces Chinampa maize yields during prolonged pre-Hispanic Era droughts?

A)Salinization of the soil
B)Algal bloom in waterways
C)Increased insect infestation
D)Lowered atmospheric nitrogen fixation

💡 Explanation

Increased evaporation during drought causes capillary action, drawing salts to the soil surface; this process is called salinization. Salinization inhibits maize growth because the increased salt concentration creates osmotic stress, therefore reducing yields rather than biotic stressors having the greater impact.
