The purpose of this study was to identify soil physical characteristics as guideline for high yield potential in ginseng cultivated field which produced 6 years root. Harvest yields of ginseng to be divided by parent rock was in order of phyllite and red shale 3.1 ㎏/3.3 ㎡ > granite and gneiss · schist 3.0 ㎏ > basalt 2.6 ㎏ > porphyry 2.2 ㎏ in upland and forest soil. Also, with classified by topography, it was in order of foot slope and alluvial fan 3.2 ㎏/3.3 ㎡ > valley 3.0 ㎏ > low hill 2.9 ㎏ > hill, lave flow and dilluvial terrace 2.8 ㎏ in survey tilth. Class determination of soil texture, it was in order of sandy loam 3.1 ㎏/3.3 ㎡ > loam and silt loam 3.0 ㎏ > clay loam 2.9 ㎏ > silt clay loam 2.8 ㎏ in survey tilth. Slope condition of farming land, in case of sloping (2~7%), it was 3.1 ㎏/3.3 ㎡ but deep sloping (15~30%) caused decreasing harvest yield. In drainage classes (excessively, well and moderately well), there was no significantly different in harvest yields. Relationship between harvest yield and soil series, Production sites as yielding 3.0 ㎏/3.3 ㎡ were seven sites, also it was contained 14 soil series. Production sites as yielding 2.5~3.0 ㎏/3.3 ㎡ were eleven sites, it was contained 16 soil series. Production sites as yielding 2.0~2.5 ㎏/3.3 ㎡ were 10 sites, it was contained 4 soil series.
