1. Why CO₂ is Important for Greenhouse Crops?
- Improves photosynthesis and plant growth.
- Increases crop yield by 20-40% under optimal conditions.
- Enhances water-use efficiency in plants.
2. CO₂ Enrichment Methods
| CO₂ Source | Effectiveness | Cost | Best For |
|---|---|---|---|
| CO₂ Tanks | High | High | Large-Scale Greenhouses |
| Burning Fuels | Medium | Medium | Commercial Farming |
| Compost & Organic Matter | Low | Low | Small-Scale Greenhouses |
| CO₂ Generators | High | Medium | Controlled Farming |
3. Best CO₂ Strategy for Different Greenhouses
- Small Greenhouses → Composting or organic material for low-cost CO₂.
- Commercial Greenhouses → CO₂ tanks or generators provide consistent enrichment.
- Sustainable Farming → Using bio-based CO₂ sources reduces expenses.
