What method can help manage pest populations and enhance soil fertility through diversity?

Crop rotation is an effective method for managing pest populations and enhancing soil fertility through diversity. By alternating different types of crops over various growing seasons, crop rotation disrupts the life cycles of pests that may thrive on specific crops. This diversity in planting can prevent pest populations from establishing and multiplying, ultimately reducing the need for chemical pesticides.

In terms of soil fertility, different crops contribute various nutrients to the soil. For instance, legumes can fix nitrogen, improving soil nutrient content when grown in rotation with other crops that may deplete these nutrients. This practice not only builds healthier soil but also promotes a more resilient agro-ecosystem.

The method stands out because it emphasizes a strategic approach to agricultural practice, leveraging ecological principles to achieve sustainable outcomes in both pest management and soil health. Other farming methods listed, such as mixed farming, cage farming, and posting farming, do not necessarily incorporate the same rotational strategy that directly enhances soil fertility and pest control through biodiversity.
