Here’s a comprehensive module on best practices for wound injection, tree health, and monitoring in agarwood plantations, designed for your Sustainable Agarwood Plantation Management & Carbon Farming Course, manuals, and Oud Academia / CI-ASASE SOPs.
Best Practices: Wound Injection, Tree Health & Monitoring in Agarwood
1. Wound Injection: Principles
Purpose: Controlled resin induction while minimizing tree stress.
Key Principles:
- Minimize injury size and number
- Target healthy, mature trees (≥5 years old)
- Maintain sterility to prevent contamination
- Ensure wounds are accessible for resin accumulation monitoring
2. Preparing for Wound Injection
A. Tools & Materials
- Drill or auger (1–2 cm diameter, sterilized)
- Fungal inoculum (single or consortium)
- Chemical elicitor solution (optional)
- Sterile wax, clay, or biodegradable plug
- Gloves, disinfectant, sprayer
B. Tree Selection
- Healthy, vigorous trunk
- No major mechanical damage or disease
- Adequate canopy and root system
3. Wound Injection Procedure
Step-by-Step
- Mark inoculation points
- Recommended: 2–4 points per trunk (depending on age/size)
- Avoid structural weakness points
- Drill hole
- Depth: 3–5 cm (species & trunk diameter-dependent)
- Diameter: 1–2 cm
- Angle: Slightly downward to prevent water pooling
- Insert inoculum
- Fungal paste or liquid suspension
- If dual-action: apply chemical elicitor around or into wound
- Seal wound
- Use wax, clay, or biodegradable plug
- Prevent contamination and moisture loss
- Label & record
- Record date, inoculant type, hole location, and tree ID
4. Post-Injection Tree Care
A. Irrigation
- Maintain soil moisture (avoid waterlogging)
- Drip irrigation or basins recommended
B. Nutrition
- Balanced N-P-K with organic amendments
- Micronutrients if leaf deficiencies appear
- Avoid high nitrogen during resin induction
C. Mulching
- 5–10 cm organic mulch around the base
- Conserves moisture and encourages microbial activity
D. Pest & Disease Management
- Monitor for secondary infections
- Apply Trichoderma / biofertilizers as preventive
- Avoid chemical fungicides unless necessary
5. Monitoring Resin Development
A. Timeline
- Initial response: 2–6 months
- Early resin formation: 6–12 months
- Full resin accumulation: 2–5 years (depends on species & method)
B. Monitoring Parameters
| Parameter | Method | Frequency |
|---|---|---|
| Resin exudation | Visual inspection of wound | Every 1–2 months |
| Wound health | Check for fungal contamination | Every 2–3 months |
| Tree vigor | Leaf color, new shoots | Monthly |
| Environmental stress | Soil moisture, canopy condition | Weekly in dry season |
C. Sampling
- Non-destructive scraping or extraction to assess resin quality
- Record location and yield for traceability
6. Common Mistakes to Avoid
❌ Drilling too deep or large holes → structural weakness or mortality
❌ Multiple wounds too close → stress accumulation
❌ Skipping sterilization → contamination by unwanted fungi
❌ Neglecting post-injection care → reduced resin yield
❌ No records → cannot track induction efficiency or ESG compliance
7. Integration with Plantation Management
- Align inoculation points with tree spacing and canopy layout
- Combine with fertility, irrigation, and agroforestry management
- Document in digital or manual farm record system for:
- Yield projection
- Carbon MRV
- Buyer traceability
8. Key Takeaways
- Controlled, minimal injury + proper sealing = optimal resin formation
- Healthy tree management (water, nutrition, mulch) maximizes resin quality
- Regular monitoring ensures early detection of contamination or stress
- Documentation supports sustainability, ESG, and carbon certification
