7.2 Data Logging for Agarwood Resin Induction

Purpose:
Accurate data logging ensures traceability, quality assessment, and optimization of microbial inoculation protocols. It supports research, regulatory compliance, and commercial plantation management.

1. Key Data Categories

CategoryData PointsPurpose
Tree IdentificationTree ID, species, age, GPS location, genotypeTraceability, selection for high-resin phenotypes
Inoculation DetailsDate, inoculation method, wound type & location, fungal strain & concentration, co-inducers usedStandardization and reproducibility of induction
Tree ResponseWound healing, sap/bleeding, discoloration, signs of stress or infectionMonitor health and stress response
Resin DevelopmentResin onset date, spread pattern, volume/weight, color, densityEvaluate efficacy of inoculation method and fungal strain
Environmental ConditionsTemperature, rainfall/irrigation, soil moisture, fertilizer applicationCorrelate resin production with environmental factors
Post-Inoculation CarePruning, pest control, nutrient supplementation, wound maintenanceEnsure tree recovery and optimal resin accumulation
Quality AssessmentPhysical (density, color, texture) and chemical (sesquiterpene/chromone content via GC-MS/HPLC)Assign resin grade and select superior trees for propagation
Harvest RecordsHarvest date, method, resin yield per wound/tree, processing notesTrack productivity and ROI

2. Recommended Data Logging Methods

A. Manual Field Logs

  • Use waterproof notebooks or printed datasheets.
  • Include pre-formatted tables for each data category.
  • Pros: Simple, low-cost
  • Cons: Labor-intensive, prone to human error

B. Digital Logging

  • Use tablets, smartphones, or GPS-enabled devices.
  • Apps: Airtable, Google Sheets, Farm Management Software, or custom databases.
  • Pros: Real-time data entry, automated calculations, easier traceability

C. Advanced Monitoring

  • Integrate sensors for soil moisture, temperature, and sap flow.
  • Link data to tree IDs and inoculation records for predictive analytics.

3. Data Collection Frequency

ParameterFrequency
Tree health / wound responseWeekly for first 2 months, then monthly
Resin onsetWeekly observations
Resin spread & accumulationMonthly or bi-monthly
Environmental dataDaily (automatic sensors) or weekly manual recording
Post-inoculation interventionsAs needed (fertilization, pruning, pest control)
Chemical profilingAt harvest or predetermined intervals for research

4. Data Management Best Practices

  1. Unique Tree IDs: Assign codes for easy tracking.
  2. Standardized Units: Use consistent units (e.g., grams, cm, mL).
  3. Photographic Records: Take periodic photos of wounds and resin spread.
  4. Backup Data: Store digitally with cloud backup to prevent data loss.
  5. Traceability: Link field data with lab analyses for GC-MS/HPLC results.
  6. Analytics: Use data to:
    • Identify high-resin phenotypes
    • Optimize inoculation timing and strain selection
    • Predict yield and quality outcomes

6. Benefits of Proper Data Logging

  • Ensures consistent, reproducible results across plantations.
  • Facilitates regulatory compliance (CITES, national permits).
  • Supports research on resin induction efficiency.
  • Provides traceable records for premium-grade resin or oil.
  • Enables data-driven decision making for inoculation strategies and post-care management.
