What is crop rotation commonly practiced for?

• A. To allow machinery to rest
• B. To prevent soil depletion and control pests and diseases
• C. To increase the area of farmland
• D. To focus solely on cash crops

Answer: (B)

Crop rotation is commonly practiced primarily to prevent soil depletion and control pests and diseases. This agricultural practice involves alternating the types of crops grown in a particular field from one season to the next. By doing so, different crops utilize different nutrients from the soil, which helps maintain soil fertility over time. For instance, legumes can add nitrogen back into the soil, benefiting subsequent crops. Moreover, rotating crops disrupts the life cycles of pests and pathogens that may thrive when a single crop is grown continuously in the same area. By varying the crops, farmers can reduce the risk of crop-specific diseases and pest infestations, leading to healthier plants and potentially better yields. The other options do not address the primary purposes of crop rotation effectively. Machinery resting and increasing area or focusing solely on cash crops do not relate to soil health or pest management, which are the core reasons for implementing crop rotation practices in sustainable agriculture.
