What is the main purpose of crop rotation?

The correct answer is d) All of the above.

Crop rotation is the practice of growing different types of crops in the same area in successive seasons. This helps to improve soil fertility, reduce pest and disease incidence, and increase crop yield.

• Improving soil fertility: Crop rotation helps to improve soil fertility by breaking up the cycle of pests and diseases. When the same crop is grown in the same area year after year, the soil can become depleted of nutrients and more susceptible to pests and diseases. Crop rotation helps to prevent this by rotating different types of crops, which each have different nutrient requirements. This helps to keep the soil healthy and productive.
• Reducing pest and disease incidence: Crop rotation also helps to reduce pest and disease incidence. Many pests and diseases are specific to certain crops. By rotating crops, farmers can disrupt the life cycle of these pests and diseases, making it more difficult for them to survive and reproduce. This helps to reduce the risk of crop losses due to pests and diseases.
• Increasing crop yield: Crop rotation can also help to increase crop yield. When the same crop is grown in the same area year after year, the soil can become depleted of nutrients and more susceptible to pests and diseases. This can lead to lower crop yields. Crop rotation helps to prevent this by rotating different types of crops, which each have different nutrient requirements. This helps to keep the soil healthy and productive, which can lead to higher crop yields.

In conclusion, crop rotation is a valuable practice that can help to improve soil fertility, reduce pest and disease incidence, and increase crop yield.
