Why are beans an important stage of crop rotation?

Beans are an important stage of crop rotation because they are legumes that can fix atmospheric nitrogen into the soil, enhancing soil fertility. This natural nitrogen enrichment reduces the need for synthetic fertilizers in subsequent crops, promoting sustainable farming practices. Additionally, beans can improve soil structure and health, helping to prevent erosion and suppress weeds. Their inclusion in crop rotation also helps break pest and disease cycles, contributing to overall agricultural resilience.
