Practising crop rotation. 3. Carrying out a large scale irrigation system. 4. Using organic fertilizers. Select the correct answer using the code given below :
- Planting a tree belt acts as a windbreak, reducing wind erosion which is critical in semi-arid areas, and can help conserve soil moisture. This is environment-friendly. 2. Practising crop rotation improves soil structure, fertility, and reduces the build-up of pests and diseases, reducing the need for chemical inputs. This is environment-friendly. 3. Carrying out a large scale irrigation system in semi- arid areas can lead to unsustainable water use, depletion of water sources, and soil salinization, making it generally not environment-friendly. 4. Using organic fertilizers improves soil health, water retention, and fertility without introducing synthetic chemicals, which is environment-friendly. 88. Deforestation is not a direct cause of:
