In this study, it was investigated that the physico-chemical properties of the sentiment from candidates sites of upland-horticultural fields in the Samangeum reclaimed tideland in order to suggest for basic data for the development of reclaimed agricultural land. The soil texture of Gwanghwal, Gyehwa, ManKyung and Okgu tidal flat appeared to be sandy loam, identically. The average of pH in sediment appeared 7.62, 7.42, 7.42 and 7.82, respectively. The average of EC in the above sites appeared 27.11, 41.0, 26.5 and 27.8 dS/m, respectively. The average of CEC appeared 12.79, 8.82, 13.27 and 10.75 cmol/kg, respectively. For the average of exchangeable sodium percentage (ESP), Gyehwa and Okgu seemed to be higher, 73.62% and 61.05%.
