Vegetation of Southeast Asia Studies of Forest Types 1963-1965

Attention is drawn to the fact that training in Soil Science
in temperate countries is inadequate for the full appreciation,
proper interpretation and management of tropical soils. There is
a brief discussion of soil erosion in Thailand.

Some results of termite activity in Thailand soils. Thai
Science Bulletin 3 (2): 29-53. illustr. April
Much has been published about the destructiveness of termites.
In many parts of Thailand these ubiquitous insects are of considerable
benefit to ff-rraers. Millions of mounds built by termites
furnish the fear,.- rs with small plots of modified soil which,
•when utilized properly, are useful for the production of tobacco,
cotton, chillies, vegetables, and mulberry leaves.
Large quantities cf calcium carbonate, in the form of concretions,.
resembling xankar, are formed by these insects. The
characteristics of the termitoriura developed by these insects and
the importance of the mounds for agricultural production are described.

Laterite, or Sila l^aeng, a peculiar soil formation. Thai
Science Bulletin 3 (3-M-* 61-77- illustr. Dec.
In gradually-sloping land, around the well-watered rice plains
of Thailand and covered by slow-growing, open forest, the ^ii is
light sandy with a layer of 'hardpan' of iron oxides and related
compounds known as 'Sila laeng 1 . This material is laterite which
has developed in the soil during the course of many ages.
The author gives a summary and conclusions on the subject,
supplemented by 20 references.
