Which long-term consequence results from repeated intensive terrace cultivation without adequate soil replenishment in Andean highlands?

💡 Explanation

When terrace cultivation proceeds without replenishment, nutrient depletion occurs because continuous cropping extracts minerals, leading to soil degradation and eventual topsoil erosion. Therefore soil erosion and reduced productivity results, rather than increased yield, decreased sedimentation, or carbon sequestration which require specific soil management conditions.
