The purpose of this study was to identify soil physical characteristics as guideline for high yield potential inginseng cultivated field which produced 6 years root. Harvest yields of ginseng to be divided by parent rock was in order ofphyllite and red shale 3.1㎏/3.3㎡ > granite and gneiss·schist 3.0㎏ > basalt 2.6㎏ > porphyry 2.2㎏ in upland and forestsoil. Also, with classified by topography, it was in order of foot slope and alluvial fan 3.2㎏/3.3㎡ > valley 3.0㎏ > low hill2.9㎏ > hill, lave flow and dilluvial terrace 2.8㎏ in survey tilth. Class determination of soil texture, it was in order of sandyloam 3.1㎏/3.3㎡ > loam and silt loam 3.0㎏ > clay loam 2.9㎏ > silt clay loam 2.8㎏ in survey tilth. Slope condition offarming land, in case of sloping (2~7%), it was 3.1㎏/3.3㎡ but deep sloping (15~30%) caused decreasing harvest yield. Indrainage classes (excessively, well and moderately well), there was no significantly different in harvest yields. Relationshipbetween harvest yield and soil series, Production sites as yielding 3.0㎏/3.3㎡ were seven sites, also it was contained 14 soilseries. Production sites as yielding 2.5~3.0㎏/3.3㎡ were eleven sites, it was contained 16 soil series. Production sites asyielding 2.0~2.5㎏/3.3㎡ were 10 sites, it was contained 4 soil series.
