Which outcome weakens ancient South American terraced farming?

💡 Explanation

A lack of crop rotation decreases agricultural yields because continuous cultivation depletes the soil nutrient levels through the mechanism of nutrient leaching, therefore plant growth is inhibited and the terrace system is weaker rather than retaining higher yields with constant planting.
