The main goal of crop rotation is to return nutrients to the soil and reduce fertilizer use. This agricultural practice involves alternating the types of crops grown in a particular area over time. Different crops have varying nutrient requirements and contributions to soil health. For instance, legumes are known for their ability to fix nitrogen in the soil, which can be beneficial for subsequent crops that require nitrogen.

By rotating crops, farmers can maintain or even enhance soil fertility without solely relying on chemical fertilizers, leading to a more sustainable agricultural system. This practice also helps break pest and disease cycles, improve soil structure, and promote biodiversity, which contributes to a healthier ecosystem. The advantages of crop rotation underscore its effectiveness in managing soil health and resource inputs efficiently.

In contrast, introducing pests to the soil would negatively impact plant health, while monoculture revolves around growing the same crop type repeatedly, which can deplete soil nutrients and isn't aligned with the benefits of crop rotation. Preventing soil erosion is vital but is not the primary focus of crop rotation compared to nutrient management.
