← HistoryWhich consequence resulted when limitations in chinampa drainage encountered high maize cultivation during seasonal rains?
A)Increased nitrogen fixation rates
B)Localized soil salinization events✓
C)Enhanced phosphorus availability
D)Decreased carbon sequestration rates
💡 Explanation
Soil salinization occurs because of capillary action coupled with poor drainage concentrates dissolved salts near the surface as water evaporates; therefore, intensive maize cultivation elevates water demand and thus salt buildup, rather than affecting nitrogen/phosphorus alone.
