Question: State three principles to be observed in a crop rotation system?

Crop rotation is the practice of growing different crops in succession on the same land to improve soil fertility and crop yield. Some principles to be observed in a crop rotation system are:

- Avoid planting crops from the same family or with similar pest and disease problems in the same spot for consecutive years. This can help reduce the build-up of pathogens and pests in the soil and prevent crop losses.

- Include legumes or other nitrogen-fixing crops in the rotation to replenish soil nitrogen levels and reduce the need for synthetic fertilizers. Legumes can also improve soil structure and organic matter content by adding biomass to the soil.

- Incorporate cover crops or green manures in the rotation to protect the soil from erosion, suppress weeds, and enhance soil fertility and quality. Cover crops can also provide habitat and food for beneficial insects and wildlife.
