Protecting crops from weeds is essential as weeds compete with crops for resources, and controlling them ensures optimal growth and yield of cultivated plants. NCERT Class 8 Science Chapter 1 Crop Production and Management

Turning and loosening the soil help in nutrient recycling. It brings nutrient-rich soil to the surface, supporting plant growth by making essential nutrients available. NCERT Class 8 Science Chapter 1 Crop Production and management

Earthworms and microbes, by turning and loosening the soil, enhance aeration and add humus, improving soil structure and nutrient availability for plants. NCERT Class 8 Science Chapter 1 Crop Production and Management
