Which outcome directly reduced soil erosion initiated using pre-Columbian terrace farming on steep Andean slopes for maize cultivation?

💡 Explanation

When terraces are constructed, slope length decrease induces reduced runoff velocity due to shorter flow paths, leading to increased water infiltration into the terraces. Therefore increased infiltration results, rather than nutrient cycling, pest resistance, or germination rate, which are less related to erosion control.
