Which agricultural outcome decreased sharply when Incan hillside terracing lost support?

💡 Explanation

Increased soil erosion occurs because bench terraces rely on terracettes reducing slope length improving stability; therefore, without wall support, the soil slid causing increased erosion and nutrient runoff, rather than maintaining stable yields or affecting pest resistance directly.
