Which agricultural outcome occurred when pre-Columbian civilizations implemented terracing on sloped maize fields?

💡 Explanation

When terracing was implemented, contour plowing reduced water runoff because stepped levels interrupt flow, thus decreasing erosion rates. Therefore, reduced erosion results, rather than increased blight, contamination, or decreased biodiversity, which depend on different factors like humidity or nutrient depletion.
