Corn, wheat, rice, field bean, soybean, cabbage, spinach, lettuce, curlycress, carrot, turnip, radish, tomato, and squash plants were grown to commercial harvest stage using as the substrate, soil pretreated with a municipal sewage sludge (1%) containing variable amounts of CdSO/sub 4/ up to 640 ..mu..g Cd/g soil. Observations included injury symptoms, yield decrement, Cd level of diagnostic tissue, and Cd and Zn content of harvested produce. Cadmium-sensitive plants such as spinach, soybean, curlycress, and lettuce were injured by soil Cd levels of 4-13 ..mu..g Cd/g soil; whereas, tomato and cabbage tolerated soil levels of approximately 170 ..mu..g Cd/g soil without exhibiting injury symptoms. Rice was tolerant at all levels tested. Leafy plants such as lettuce, spinach, and turnip greens (tops) accumulated 175 to 354 ..mu..g Cd/g; whereas, fruit and seed tissue of plants under comparable treatment, with the exception of soybean, accumulated no more than 10 to 15 ..mu..g Cd/g tissue. The concentrations for soybean extended up to 30 ..mu..g Cd/g tissue. Paddy rice exhibited no ill effects for soil Cd treatments up to 640 ..mu..g Cd/g soil. Grain of plants under the 640..mu..g Cd/g treatment contained 2 ..mu..g Cd/g tissue. DPTA-extractable Cd correlated (r=0.99) with the level of CdSO/sub 4/ added to the substrate.
