  1. It helps control pests and diseases

  2. It improves soil structure

  3. It reduces soil erosion

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Crop rotation involves growing different crops in sequence on the same land, which helps control pests and diseases, improves soil structure, reduces soil erosion, and maintains soil fertility.
