Which problem limited the agricultural output of inclined terraces in the pre-Columbian Andes?

💡 Explanation

When inclined agricultural terraces experienced rising groundwater, capillary action drew salts to the surface, leading to salinization as water evaporated, thereby reducing fertility. Therefore salinization resulted, rather than erosion, leaching, or solar exposure which require rainfall patterns, soil composition and insolation issues respectively.
