How does crop rotation benefit soil health?

Crop rotation significantly enhances soil health by breaking pest and disease cycles, which are often linked to growing the same crop in the same location year after year. Different crops can have varying nutrient demands and root structures, which helps to prevent nutrient depletion by diversifying the biological and physical characteristics of the soil. For instance, legumes can fix nitrogen in the soil, which benefits subsequent crops by improving overall soil fertility. Furthermore, by rotating crops, farmers can disrupt the life cycles of pests and pathogens that thrive on specific crops, effectively reducing the reliance on chemical pesticides and promoting a more balanced ecosystem.

The correct answer acknowledges the multifaceted benefits of crop rotation, emphasizing not just pest and disease control but also enhanced soil fertility, which is crucial for sustainable agriculture.
