Which process limits crop yields because degradation occurs fastest in terraced Andes fields used heavily for maize cultivation?

💡 Explanation

Topsoil erosion limits yields on steep slopes because terraces capture rainfall, which leads to concentrated runoff and gullying, thereby accelerating soil loss and nutrient depletion; therefore the yields drop significantly rather than increase via irrigation.
