Which limiting factor decreased maize yield in ancient terraced agricultural systems despite successful soil conservation?

💡 Explanation

When continual planting occurs without nutrient replenishment, terraced soils lose essential elements because water runoff facilitates nutrient leaching down terraces, ultimately depleting the nutrient profile in the upper plots. Therefore, yield suffers due to nutrient leaching, rather than pest, frost, or pollination issues, which are distinct and separate limiting factors.
