ABSTRACT This report describes coil survey activities in S: ¿ju Gun whichwere part of the Korea Soil Survey conducted by the Government of the Republic of Korea with the assistance of the Unied Nations Special Fund1/. The field work of the survey was done during the period from July1967to December1968. The entire area of the Gun (125 928hectares) was mapped in detail, including paddy lands, upland crop fields and forest lands. Together with the accompanying map, which is printed at a scale of1:250000,the reporpresents an inventory of soil and soil conditions in the surveyed area. Individual soils are described and laboratory datv, for representative profile,3 are iven. The report includes soil descriptions and interpretations, and provide data and recommendations for specific lana resource a,nalysis and planning. The basic information about the soils is interpreted fo ïlication to the various aspects of agriculture in the area, including land use adjustment, reclamation and develobment, increasing production, ard the improvement and conservation of lands according to their capabilities. To show general land use potential the soils of the area are placed in seven land caoability classes showing limitations and choices for practical use. The soils in each capability class are given, the suitability and limitations for cultivated crops and pasture are described, and mantIsment practices required for higher yields aro suggested. About 19 600 hectares or 62 percent of the cultivated land is used for paddy rice. Management of the soiTs for paddy rice is discuased and the soils are placed in four paddy suitability groups, indicating progressively greater limitations in the use o? the land for rice. The United Ratio Special Fund and the Expz ted Programme of Technical Assistance were merged tc the United Nations Development Programme on 1 January1966. Grateful acknowledgement is made of the keen interest and full support extended throughout the project towards the soil survey team by the Ministry of Agriculture and Forestry, the Government Cooperating Agency and by countorpar'6 staff.
