Which agricultural outcome improved with Inca terracing via reduced erosion?

💡 Explanation

Soil erosion reduces fertility without interventions; terracing causes sediment trapping, limiting runoff, because the mechanism of stepped topography slows water flow. With less runoff, nutrient loss is reduced, therefore soil on terraces retains vital minerals rather than faster exhaustion on sloped land.
