The main purpose of crop rotation is to improve soil fertility and disrupt pest cycles, which makes it a critical practice in sustainable agriculture. By alternating different crops in a field over various growing seasons, this method enhances soil health—certain crops, like legumes, can fix nitrogen in the soil, contributing to its fertility. Additionally, rotating crops can reduce the buildup of pests and diseases that often occurs when the same crop is grown repeatedly in the same place. This practice helps mitigate the risk of crop loss due to pest infestations and improves overall farm resilience. Thus, the benefits of crop rotation encompass enhancements to both soil quality and agricultural biodiversity, forming a foundational aspect of integrated crop management strategies.
