| 内容記述 | Reduction of the cadmium (Cd) content of vegetables is important for food safety and vegetable production in Japan. I examined the effects of three kinds of organic material (composted cow, pig or chicken manures) on the Cd content of spinach and on the dynamics of Cd forms in the soil. I used an Andosol and a mixed soil (a mixture of Andosol and Cd -contaminated Yellow Soil) for the experiment. I planted the spinach in pots filled with the soil, into which I had mixed the organic material (23.5gL^1), and then grew the plants in an incubator for 41 days. Control pots received no organic material. After harvest, I analyzed the spinach Cd content, soil pH, and soil total carbon (T-C) content, as well as the soil concentration of Cd extracted by using different methods. 1. The Cd content of the spinach planted with organic Pig manure application appeared to be the most effective for reducing spinach Cd content. 2. The pH values of the soils to which organic materials had been applied remained high. The amount of available Cd (0.01 M HCl extracted form and exchangeable form) in the soil was reduced by the application of composted pig or chicken manure. 3. Negative correlations between soil pH and available soil Cd content were observed. Similarly, there were negative correlations between soil T-C and available soil Cd. There were no correlations between soil pH or soil T-C and the content of other Cd forms. 4. There were no correlations between soil Cd content and spinach Cd content. These results indicated that application of organic materials could sustain pH levels and increase T-C content. It also reduced the available Cd content of the soil. This suggests that application of organic material (especially composted pig manure) efficiently reduces the risk of Cd contamination in spinach production. | |||||
