• If a farmer plants wheat one year, corn the next, and soybeans the third, what practice is being implemented?

  Crop rotation.
• How does crop rotation help in pest management?

  It breaks pest and disease cycles by changing the host plants available to pests.
• What are the benefits of crop rotation?

  - Improved soil health - Pest and disease control - Weed suppression - Increased yield - Risk management - Reduced reliance on chemicals
• How does crop rotation improve soil health?

  Different crops have different nutrient needs and root systems, which helps maintain soil structure and fertility.
• If a farmer rotates crops to manage pests, what is the primary benefit they are seeking?

  To disrupt the life cycle of pests by removing their preferred host plant.
• What is the Norfolk four-course system in crop rotation?

• What is the effect of rotating crops on microbial diversity in the soil?

  Different crops support various soil microorganisms, enhancing overall soil biodiversity.
• How does crop rotation contribute to erosion control?

  Some crops provide better soil cover, reducing erosion risk.
• What is a key advantage of using a deep-rooted cover crop over leaving a field fallow?

  It actively improves soil structure and adds organic matter.
• What is the primary benefit of crop rotation for farmers?
