This study was carried out to examine the physicochemical characteristics of dredged soils in reservoirs. Surveys and analyses of basic materials were made on 241 of 2,328 reservoirs in Chonbuk province through 2 years from December 1994 to November 1996. The results of this study are summarized as follows : 1. Soils were classified as 15 types according to physical properties, and some soils contain comparatively high percentage of sand and gravel. Considering only soil textures, useful and economical soils as aggregate are approximately 25% in all, and the other soils are arable for farm planting. 2. The results of chemical analyses of soils showed on the average 5.9 in pH, 1.lmmhos/cm in ECe, 14.6me/l00g in CEC, 460.0ppm in T-N, 119.0ppm in T-P, 264.9ppm in K, 134.2ppm in Na, l,335.0ppm in Ca, 575.9ppm in Mg, 486.Sppm in Fe, 57.7ppm in Mn, 3.3ppm in Cu, 21.9ppm in Zn, 0.49ppm in As, 0.34ppm in Cd, 0.O3ppm in Hg, 1.7% in OM, respectively. 3. General chemical components, heavy metals, organic matter contents were analyzed as similar to tlie mean values of common soils, therefore it was considered to be no significant effects on crop growth in the chemical properties. 4. Accodingly, the physicochemical characteristics of soils ought to be analyzed accurately before dredging for effective using of dredged soils. And it will be more effective, if the dredged soils are used with proper balance among each content of components with considering to the physicochemical properties of common soils.
