What is crop rotation?

Crop rotation is a farming practice that involves alternating the types of crops grown in a specific field over different growing seasons. This technique is beneficial for several reasons, particularly related to soil health and fertility. By rotating crops, farmers can break pest and disease cycles, as different crops attract different pests and pathogens. This reduces the reliance on chemical pesticides and promotes a more sustainable approach to agriculture.

Additionally, different crops have varying nutrient requirements and can contribute to soil enhancement. For instance, leguminous plants can fix nitrogen in the soil, benefiting subsequent crops that require higher nitrogen levels. Consequently, crop rotation improves soil structure, increases biodiversity, and reduces soil erosion, leading to more sustainable farming practices.

The other choices do not encompass the definition or benefits of crop rotation. Planting the same crop each year can deplete specific nutrients and increase pest pressures, while using only genetically modified seeds does not directly relate to soil management practices. Planting multiple crops in a single season can refer to intercropping, which is different from the practice of rotating crops over seasons.
