| Abstract | Abstract The electromagnetic induction terrain conductivity meter, "EITCM", has been used for the salinity assessment in salt-affected soils in northeastern Thailand. This paper briefly discusses the applicability of the electromagnetic method for delineating the salt distribution within the landscape and determining the salt content in soil at the depth up to 30 m. This information together with hydrological data and present landuse is useful for the base of the salinity management in northeastern Thailand. A case study presented the results of the use of the electromagnetic terrain conductivity meter in some major salt-affected soils of Nakhonratchasima province. The results of the investigation revealed that the source of salt in the process of soil salinization underlies the salt-affected soils. High-elevated areas play an important role for the water supply in the process of soil salinization. Variations of the reading might be due to the salt content, moisture content and soil type. Accuracy of the reading must be carefully considered when the survey for soil profiles is carried out in the areas where high clay content and low moisture content. |
