Abstract:

The soil survey of the Chiang Mai study area was conducted during the period October 1965 to January 1966, and covered an area of approximately 3,706 sq km 1,431 sq mi. Reconnaissance was made along all accessible roads and tracks. Soils were studied at road cuts and at exposures along drainage channels. In areas of good accessibility, borings and profile pits were made in order to study the soil in greater detail. Approximately 15 observations per square kilometer were recorded. Detailed field data were mapped on air photos at varying scales from 125,000 to 155,000, then transferred from the air photos to series L 708, Army Map Service topographic maps at a scale of 150,000.
