Which outcome accelerated soil depletion on Andean agricultural terraces following the Spanish conquest?

💡 Explanation

When the Spanish introduced livestock (sheep, goats) to the Andes, overgrazing occurred because the animals compacted the soil on the agricultural terraces, damaging their structure. Therefore, soil depletion accelerated, rather than crop rotation, fertilizer, or deforestation affecting primarily cultivated lands.
