The practice of alternating different crops on the same piece of land to keep soil healthy and disrupt pests is crop rotation. By changing what is grown from one season to the next, each plant uses nutrients in different ways, and legumes can even add nitrogen back into the soil. This diversity helps prevent nutrient depletion, improves soil structure and moisture retention, reduces weed pressure, and breaks pest and disease cycles that depend on a single crop. For example, planting corn one year, followed by a legume like beans or peas, then a different crop the next year, helps maintain soil fertility and lowers pest pressure over time.

The other options describe related farming ideas but not this specific practice. Mixed crop and livestock systems integrate crops with animals and may involve rotations, but the term focuses on rotating crops alone to improve soil health. Plantation agriculture centers on large-scale monoculture of a single crop for export, not rotation. Market gardening refers to intensive, small-scale vegetable production for local markets and is defined more by scale and crops than by a rotation principle.
