Which benefit occurred due to terrace construction combined with sophisticated irrigation in Inca maize cultivation?

💡 Explanation

When terraces with controlled water flows were implemented for maize, nutrient stratification minimized erosion due to cascading water flow, enhancing multi-seasonal yield. Therefore, long-term nutrient depletion was mitigated, in contrast to waterlogging control, wind breaks or buffering fluctuations related predominantly for arid regions rather than the vertical impact zones targeted by the agricultural improvements.
