To get the basic information about ginseng seedling production, yield of ginseng seedling and soil physicochemical components of Banyangjik (semimodified soil) nursery in 29 fields were investigated. The number of available seedling per Kan (Kan means 180x90cm area) is 362+-226. Root weight per seedling was negatively correlated with ammount of fine and extremely fine sand. Positive correlations were shown between pH and OM, K, Ca and Mg, and also between EC and Ca, Mg and ammonium and nitrate nitrogen in soil of nursery. There were significant linear relations between root weight and OM, K, Ca and Mg in soil of nursery. On the other hand, quadratic relation was held between the root weight and P2O5, but the root weight had no correlation with nitrogen. The nitrogen contents of soil might not influence the growth of ginseng seedling as greatly as those of P2O5, K and Ca. The contents of P2O5, K and Ca in root increased with increase of the contents of P2O5, K and Ca in soil of nursery, respectively. It showed linear correlation between root weight and P2O5 and Ca, otherwise quadratic correlation between root weight and K in root
