History

Which consequence occurred in pre-Columbian agriculture when chinampa construction ceased?

A)Increased soil alkalinity and leeching
B)Reduced arable land availability
C)Accelerated soil erosion from rainfall
D)Greater demand for terrace irrigation

💡 Explanation

Increased soil alkalinity and leeching followed chinampa abandonment because disruption of capillary action increased salt concentration to the surface. This process is known as salinization; therefore, alkalinity increased rather than decreased fertility that well maintained chinampas provided.
