Final answer:
Crop rotation and intercropping are farming practices that improve soil nutrient levels, manage pests, and increase productivity.
Step-by-step explanation:
Crop rotation is a farming practice where different crops are planted in a planned sequence over time on the same field. This helps improve soil nutrient levels, break crop pest cycles, reduce production risk, and manage resources more efficiently. Another farming practice related to this is intercropping, where two or more crops are grown in close proximity to promote soil improvement, biodiversity, and pest management. Both of these practices have advantages such as increased productivity, reduced pesticide costs, and protection of water quality.
