A study was made to clarify the topographical and physical characteristics of ginseng field in terms of soil science and to find the relationship between soil characteristics and ginseng growth, as well as yield ginseng root. Forty-nine farmers' red ginseng field of ginseng growing area were chosen for this study and investigated for two years. Ginseng fields with high yield which represent the more than 1.8 kg of ginseng root per 3.2m2 were found in soil series of Bancheon, Yeongog, Weongog, etc., whose texture were the clay loam to clay soil. On the other hand, ginseng field with low yield were observed in soil series of Seogto whose texture was loamy soil with high content of gravels. Soil of ginseng field with high yield had higher content of clay, silt, soil moisture and soil pore as compared with soils of low yields. These soil characteristics were positively correlated with stem length, stem diameter and root weight of ginseng plant and negatively correlated with rate of missing plant. The adequate ranges of soil 3 phases from high yield ginseng field were 40 to 50% of solid phase, 22 to 35% of liquid phase, 25 to 35% of gaseous phase in top soil and 45 to 55% of solid phase, 28 to 30% of liquid phase, 15 to 20% of gaseous phase in subsoil, respectively.
