2.5 preventing soil contamination during agarwood harvest

Here’s a detailed guide on preventing soil contamination during agarwood harvest, which is critical for preserving resin quality and hygiene:


1. Why Soil Contamination Matters

  • Resin-rich agarwood is highly valuable, and soil contamination can:
    • Introduce dirt, sand, and debris that reduce market quality.
    • Increase risk of fungal or bacterial infection during storage.
    • Complicate processing for chips or essential oil extraction.

2. Best Practices During Harvest

A. Prepare the Ground

  • Clear the harvest area of rocks, mud, and loose soil.
  • Lay clean tarps, mats, or wooden planks where logs will be placed.
  • Ensure drainage to avoid pooling water around harvested wood.

B. Minimize Direct Contact

  • Avoid dragging logs or branches on soil.
  • Use manual lifting, rollers, carts, or forklifts to move wood.
  • If dragging is unavoidable, use clean planks or rubber mats as a barrier.

C. Cutting Position

  • Cut resin-rich sections off the ground using:
    • Saw horses, supports, or tripods for trunk and large logs.
    • Elevated branches with ropes or pulleys.

D. Cleaning Tools & Hands

  • Brush off sawdust, soil, or debris immediately after cutting.
  • Wash or sanitize chainsaw chains, chisels, and cutting boards.
  • Wear clean gloves to prevent transferring dirt to freshly cut wood.

3. Handling & Transport

  • Use tarps, plastic crates, or pallets to store logs immediately after cutting.
  • Separate resin-rich wood from non-resinous or potentially contaminated wood.
  • Avoid stacking logs on wet soil, which can lead to moisture absorption and microbial growth.

4. Post-Harvest Measures

  • Lightly brush off residual dirt before processing.
  • If possible, air-dry or sun-dry logs on elevated racks.
  • Monitor for mold or fungal growth, particularly in humid environments.

5. Summary Table

StepPreventive Measure
Ground preparationClear debris, lay tarp or planks
CuttingKeep resin-rich wood elevated, avoid direct soil contact
Tool hygieneClean/sanitize cutting tools
HandlingUse carts, rollers, or forklifts
StorageElevate logs, separate resin-rich sections, dry properly

Key Principle: Always treat resin-rich wood as high-value and sensitive—even minor soil contamination can reduce its commercial or aromatic quality.
