Part 1. Description of Fertility Characteristics川口 桂三郎, 久馬 一剛1974 年 12 巻 1 号 p. 3-24

ジャーナル フリーThe results of laboratory studies conducted on 410 sample soils collected from different countries of tropical Asia have been described. The items taken up in this paper are those routinely analyzed for characterization of fertility status of paddy soils, such as pH, total carbon, total nitrogen, ammoniacal nitrogen, total and available phosphorus, cation exchange capacity, exchangeable cations, and available silica. A histogram and/or a table showing country means and other statistics were given for each item.
Many of these characters are correlated with each other and with material as well as climatic and local relief features. This aspect of the data will be dealt with in one of the papers to follow.抄録全体を表示PDF形式でダウンロード (1367K)

派生村形成の社会過程矢野 暢1974 年 12 巻 1 号 p. 49-65

ジャーナル フリーThis is the fifth of the serial articles titled "Socio-Economic Basis of Social Communication in Southern Thailand."
The main aim of this article is to present an analytical view on the social processes of "Baan-mai formation" in a Thai-Islam community in Southern Thailand.
This article also incidentally aims to propose a hypothetical method to reproduce the history of a village in Thailand.
One of the basic characteristics of a Thai village is that, through the familiar habit of squatting ownerless land, new hamlets are easily formed inside or outside the original village boundary. It is, in a sense, a social mechanism by which a good balance is constantly achieved between population and land holding. This sequence of "baanmai formation" is one of the basic themes of the history of a Thai village. The easiness of the "baan-mai formation" has long functioned to obscure the actual extent and range of a village community in Thailand as well as to keep the Thai social structure fairly loose.
In the village of Don-Khilek, where the author conducted a field survey on the subject, the "baan-mai" formation has taken place in three different waves at three different junctions in the course of its history. Don-Khilek originally consisted of a single hamlet, but it has produced seven or eight different hamlets in the past eighty years.
The phenomenon of "baan-mai" formation has to be analyzed in a two-partite way; that is, the physical process of a new hamlet formation on the one hand, and the social process of seperation of community activities like religious rituals, on the other.抄録全体を表示PDF形式でダウンロード (2068K) -

Their Possible Origin as Deduced from Field EvidenceSomsri Sinanuwong, 高谷 好一1974 年 12 巻 1 号 p. 105-120

ジャーナル フリーThe selected profiles of saline soils in the vicinity of Khorat, Northeast Thailand, are described. Geomorphological interpretation of the profiles make the following points clear regarding the origin of the salt :
1) Some shales and sandstones belonging to the Mahasarakam Formation of the Mesozoic Khorat Group retain in-situ salt even when they are located as little as 1 to 2m below the ground surface. The salt is released by erosion and weathering. This is the mechanism of extraction of salt from the source rock.
2) Only the Mahasarakam Formation seems to be a source of salt. Other rocks, including the older formations of the Khorat Group, appear not to contribute the development of salinity in the area, because they do not contain salt.抄録全体を表示PDF形式でダウンロード (1025K) -

ジャーナル フリーThis article is dealing with the cinnamon tree cultivations in Batusangkar, Padang Highlands, West Sumatra based on writer's field survey in Apri 1971.
In western Sumatra, three areas, Mt. Kerinci, Padang Highlands and South Tapanuli are famous for cinnamon tree (Cinnamomum burmanni BL.) cultivation. The products are known as Padang Cinnamons or cassia vera in crude drug markets. Mt. Kerinci areas are said to produce the cinnamons of best quality and almost the half of the total amount of Padang Cinnamons.
In Batusangker, Padang Highlands, cinnamon trees were originally cultivated in the wider areas above 500m in altitude, however, recently the cinnamons were replaced by the clove trees in the lower parts than 800m.
Usual methods for stock multiplication are to raise seedlings in nursery. Techniques deviding the shoots from old stumps are also practised. Pruning is adopted in order to obtain a clear long bole with smooth bark and to stimulate high growth.
The harvested barks are graded into three classes according to their quality by cultivaters. Village brokers and whole sale dealers in Padang put the collected barks into seven grades.
A great deal of Padang Cinnamons are exported directly to U.S.A.抄録全体を表示PDF形式でダウンロード (1460K)
