Abstract
RDA has been conducting soil survey for farmland all over the korean countries (1964-1999), including small islands and areas of the civilian passage restriction line (2000-present). We conducted a soil survey in Dokdo and Ulreungdo islands and found a new soil series "Dokdo" in Dokdo island. Soil properties of Dokdo were similar to those of Ulreungdo. Representative profiles of Dokdo soil was located at the south 20m of Daehan peak on Seodo (longitude $131^{\circ}$51'53", latitude $37^{\circ}$14'35"), Dokdo. The soil series "Dokdo" was interpreted as the soils were derived from trachyandesite, trachyte, rhyolite, and tuff. The soil properties of Dokdo series were classified as different ones from Korean soil series previously. The soil depth of Dokdo series was very shallow (0-20cm) and soil layer was consisted of very dark brown (10YR 2/2) rocky sandy loam and dark brown (7.5YR 3/2) gravelly silt loam in AC layer. The soils of Dokdo displayed characteristics of a mesic temperature regime, similar as Ulreungdo soils, which were classified as coarse loamy, mesic family of Lithic Udorthents. The total area of Dokdo soil was 18.7 ha, containing Dongdo (7.3 ha), Seodo (8.9 ha), and the others (2.6 ha). The area of Dokdo series in Dokdo was 10.47 ha (Dongdo 4.13 ha, Seodo 6.34 ha) and 808.56 ha in Ulreungdo, where the total soil area was 7,256 ha.
