Which practice helps improve soil fertility and structure over time?

Crop rotation is a practice that significantly enhances soil fertility and structure over time. This technique involves alternating the types of crops grown on a particular piece of land in sequential seasons. Each type of crop contributes differently to the soil ecosystem. For instance, legumes can fix nitrogen in the soil, improving nutrient availability for subsequent crops. Additionally, varying root structures from different plants can help improve soil aeration and reduce compaction, leading to better water infiltration and root growth.

This method also disrupts pest and disease cycles, since many pests and diseases are crop-specific. By rotating crops, farmers can reduce the buildup of these problems, which supports healthier plants and reduces the need for chemical interventions. Overall, crop rotation promotes a more balanced and resilient agro-ecosystem, enhancing both soil quality and agricultural productivity sustainably over time.
