Which outcome commonly resulted when historic chinampa farmers neglected proper canal maintenance surrounding maize crops?

💡 Explanation

Soil salinization reduced maize yield because the capillary action draws salts to the surface with evaporation, therefore fields become less fertile rather than benefiting from nutrient cycling.

• Which structural failure increases in ancient Inca rope bridges when subjected to prolonged cyclical loading?
• Which vulnerability increased when thin-cut tesserae mosaics faced thermal cycling in the Basilica cistern?
• What catastrophic outcome increased rapidly, when 13th-century warjunks overloaded trebuchets intended to fire crude gunpowder projectiles?
• Which maintenance outcome primarily prevents Roman roads ('viae') from subsurface weakening when seasonal freezing occurs?
• Which problem often reduced crop yields despite well-engineered Mesopotamian irrigation?
• Within Mughal gardens, which outcome accelerates water feature degradation due to capillary action?
