Soil and greenhouse gas laboratory – Bogor

It is equipped with facilities to analyze soil and vegetation properties and greenhouse gas concentrations and fluxes.

Analysis

The analyses that can be run in the soil laboratory are:

1. Sample preparation – Drying, sieving, crushing and mixing soil/biomass sample
2. pH measurement
3. Sample extraction for specific analysis that cannot be done in CIFOR laboratory (i.e. for ammonium-nitrate analysis)
4. Gas analysis – measuring concentration of CO₂, N₂O and CH₄ (the analysis should be done by our technician.

Analytical equipment

1. Gas chromatograph:
   instrument to measure soil N2O and CH4 gas concentrations (Shimadzu 14A equipped with ECD Detector, FID Detector and autosampler)
2. CO₂ analyzer:
   instrument to measure soil respiration in-situ (IRGA-LICOR 840/840A, EGM-4 PP System)
3. Near Infrared (NIR) Spectrograph:
   This is a portable instrument that is designed for obtaining in-situ and ex-situ high spectral resolution reflectance measurements in the visible and shortwave infrared wavelengths (350 nm to 2500 nm) for measuring carbon content from soil samples (ASD fieldSpec-4)

We also have the supporting equipment to prepare and store samples:

1. Mixer mill:
   Instrument for crushing and mixing sample of soil and vegetation (Retsch MM 200)
2. Oven for drying soil and vegetation samples (Binder FED 720 and Memmert UNB500)
3. Field sampling and survey equipment (GPS, auger, barometer, soil thermometer, etc.)

Tree ring laboratory – Bogor

The laboratory is equipped with instruments to analyze and photograph tree rings (tree growth zones). The microscope can also be used to study soil macrofauna.

Equipment

1. Tree increment borers: equipment to collect tree stem cores for further analysis.
2. Bernardo wood sanding machine: equipment to polish stem discs.
3. Leica Microsystem: microscope, camera and computer programme to analyze and capture images of growth zones / tree rings and macro-fauna.
4. Lintab 6: equipment to count and measure the width of tree rings (Figure 11)
5. Epson Scanner: equipment to scan images of tree stem cross section /rings.

Analysis

Tree ring laboratory covers analysis of tree rings/growth zones and macrofauna including:

1. Tree rings number
2. Tree ring width
3. Tree growth zone types
4. Tree growth zone distinctiveness
5. Soil macrofauna identification until ordo level
