← HistoryWhich advantage results when maize monoculture exceeds soil nutrient limits in post-Columbian North America?
A)Resilience increases against fungal infection
B)Beneficial soil bacteria thrive rapidly
C)Crop support increases after lodging
D)The rate of soil erosion accelerates✓
💡 Explanation
Extensive maize monoculture depletes nitrogen and potassium; the rate of soil erosion accelerates because reduced plant cover and depleted organic matter weaken soil structure, therefore soils erode faster as binding root networks decline rather than remaining stable.
