A. To increase pest population B. To decrease soil fertility C. To maintain soil fertility and reduce pests D. To promote soil erosion E. To increase water logging
Correct Answer: C
Explanation
Crop rotation is an agricultural practice where different types of crops are planted in succession on the same land. This technique helps maintain soil fertility by varying the nutrient demands of different crops and breaking the life cycles of pests and diseases. For example, legumes can fix nitrogen in the soil, benefiting subsequent crops that require high nitrogen levels.
