The germination and growth of radish and chiness cabbage in soils treated with Cr, Ni, Cd, Cu, and Zn at 20, 50, 100 and 200 ppm were determined. The germination of radish and chiness cabbage in soils was greatly affected by addition of Ni and Cr at 200 ppm, but almost not at all by treatment with Cd, Cu, and Zn even 200 ppm. The injury to the growth of crops was generally the highest with Cr, followed by Ni, Cd, Cu, and Zn, and more with chiness cabbage with radish. Serious crop injury appeared at 20 ppm of Cr, 50 ppm of Ni, Cd and Cu, and 200 ppm of Zn on radish, and at 20 ppm of Cr, Ni, Cd and Cu, and 200ppm of Zn of chiness cabbage. However, crop inhibition decreased greatly with addition of compost and lime.
