The management practice of alternating different crops to maintain soil health and conserve water is called what?

• A. Monoculture
• B. Crop rotation
• C. Agroforestry
• D. Deforestation

Answer: (B)

Alternating different crops in the same field over time is crop rotation. This practice keeps soil healthy by balancing nutrient use—different crops take up nutrients in different ways, and including legumes can add nitrogen back into the soil. It also helps break pest and disease life cycles and improves soil structure, which enhances water infiltration and retention, aiding water conservation. Monoculture repeats the same crop and can deplete nutrients and raise pest risk; agroforestry mixes trees with crops; deforestation is the removal of forests.
