Which outcome affected Mesoamerican agriculture when early maize varieties faced limitations in nitrogen uptake from soil?

💡 Explanation

When early maize could not effectively uptake nitrogen, nitrogen fixation via crop rotation became crucial, because intercropping legumes replenished soil nutrients. Therefore, crop rotation with legumes increased, rather than terracing which addresses erosion, amaranth solely or artificial island creation that addresses land constraints and only indirectly impacts the uptake issue.
