Natural Fertilizers:
- Compost and manure enrich the soil with nutrients.
- Biochar improves water retention and microbial activity.
Testing and Monitoring Soil Health:
- Regular soil testing to track pH and nutrient levels.
- Use of apps and soil sensors for real-time analysis.
| Practice | Key Benefit |
| Composting | Builds organic matter. |
| Biochar Use | Retains water and nutrients. |
