These experiments were conducted to investigate some effects of the soil fumigants Dow-fume MC-2, Cylone, TeloneC-17, and D-D on the growth response of the Korea ginseng(two-year old), Panax ginseng C.A. Meyer, and the chemical composition of the plants. Fumigant treatment increased growth of roots, stems, and leaves. The increase of root growth rates ranging from 2.8 to $58.7\%$ in fresh weight and 8.1 to $63.8\%$ in dry weight were observed in the 2-year old ginseng plants grown in the old ginseng soil treated with the different soil fumigants. The chemical analysis of inorganic elements such as N, P, K, Ca, Mg, Na, Fe, Mn, and Zn was made for the roots, stems and leaves of the 2-year old plants. The increases or decreases of content of the elements were observed, and their contents of each of the elements were changed with the kind of fumigants, part of the plants, and soil depth of the fumigant treatments, but their changing tendencies were not steady.
