Abstract

The purpose of this research was to study the factors affecting the occurrence of acid sulfate soils in Ongkharak District and to study the characteristics of acid sulfate soil types. The formation process and problem conditions of acidic soils are examined to find the approach to managing acidic soil in the area of Ongkharak district. The data was studied from topographic maps on a scale of 1: 50,000 and geologic maps on a scale of 1: 250,000. Land use maps, satellite images, data from the Geological Department, including the Department of Mineral Resources, the Department of Land Development, and meteorological data, together with data from questionnaires from local farmers, using the Geographic Information System, are used as a tool for the study. The results of the study found that the factors influencing the occurrence of acidic soil around Ongkharak District consist of the geological and geological structure, rock hierarchy of Nakhon Nayok Province, topography, climate characteristics, soil characteristics, sea-level changes, and land use.
