Teak (Tectona grandis) is a valuable indigenous tree species in Thailand. Teak wood products are used in making high quality furniture and as building material for houses, etc. It is one of several economic tree species suitable for farm forestry management, and plays a vital role in promoting forest restoration and regional development, thanks to rapid tree growth and high timber prices. Teak has several characteristics, including affinity to specific soil types and conditions; hence future yield depends on site suitability for teak plantation. Decision support information on determining site suitability is important to teak farmers. There had been no such maps that quantitatively showed soil suitability for teak plantation; thus, not a few farmers came to grief after realizing that they had planted on unsuitable sites. Therefore, the Japan International Research Center for Agricultural Sciences (JIRCAS) has carried out a joint research project with the Royal Forest Department (RFD) in order to promote teak farm forestry, and contribute to the improvement of the rural livelihood.

‘Soil suitability map for teak plantation and ‘Yield table for Teak plantation in the Northeast of Thailand’ shown here are products of the RFD-JIRCAS joint research project. The products are described in Thai for Thai farmers. English version of primary parts is available below with original version to give an explanation.

Notice with regard to use

  1. The soil suitability map for teak plantation covers Udon Thani, Nong Bua Lam Phu, Chaiyaphum, Khon Kaen, Buri Ram and Ubon Ratchathani Provinces in the Northeast of Thailand.
  2. Based on field surveys and soil group map of Thailand, which is developed by the Land Development Department, Thailand, the Soil suitability class (SSC) for teak plantation was developed. The SSC is divided into 5 ranks, ranging from 1 (very well suited) to 5 (unsuited). Limitations are attached to the SSC 2-5 to show disadvantage such as n, f, g, d (n: nutrition, f: flooding, g: gravel, d: drainage). The area of slope complex (SC) and water area (W) on the soil group map is not covered. Photographs of soil conditions are also appended in the map to consider soil suitability in the field.
  3. The SSC is equivalent to the site quality class which is shown on the Yield table for Teak plantation in the Northeast of Thailand. So you could project the future yield of stand by combination usage of the soil suitability map and yield table.
    SSC Site quality class Site index
    1 1 30
    2 2 26
    3 3 22
    4 4 18
    5 5 14
  4. Actual teak growth might be different from the SSC because of effects of management and maintenance.
  5. For the map, topographical vector maps (L7018) with a scale of 1 to 50,000 of the Royal Thai Survey Department, Ministry of Defence are used to show landmarks, including roads, hydro lines and administrative areas.
  6.
