← HistoryDuring early maize cultivation, which outcome resulted when crop rotation wasn't practiced?
A)Soil nutrient depletion increased rapidly.✓
B)Genetic diversity improved markedly.
C)Herbicide resistance developed gradually.
D)Harvest yields remained indefinitely stable.
💡 Explanation
Continuous maize cultivation without rotation exhausts soil nitrogen leading to decreased yields; this is due to nutrient drawdown. Farmers rotated crops to replenish nutrients, rather than dealing with declining harvests as nitrogen becomes deficient.
