What is the main purpose of crop rotation?

Increasing yield
Reducing pest and disease incidence
Improving soil fertility
All of the above

The correct answer is: d) All of the above

Crop rotation is the practice of growing a series of different crops in the same area in sequential seasons. It is one of the oldest agricultural practices, and it has many benefits.

One of the main benefits of crop rotation is that it helps to increase crop yields. When different crops are grown in the same area, they use different nutrients from the soil. This helps to prevent the soil from becoming depleted of nutrients, which can lead to lower crop yields.

Crop rotation also helps to reduce pest and disease incidence. Many pests and diseases are specific to certain crops. By rotating crops, farmers can help to break the life cycle of these pests and diseases, which can reduce their impact on crops.

Finally, crop rotation helps to improve soil fertility. When different crops are grown in the same area, they add different nutrients to the soil. This helps to keep the soil healthy and productive.

In conclusion, crop rotation is a beneficial agricultural practice that helps to increase crop yields, reduce pest and disease incidence, and improve soil fertility.
