Outline of Final Research Achievements

In order to reduce the amounts of Cd uptake by rice plants, insolubilization of Cd as cadmium sulfide is an effective measure. We found that average ratio of insoluble cadmium sulfide in flooded soil was not always predictable by the thermodynamic constant. This was because cadmium sulfide was unevenly distributed around rice roots and amendment materials depending on the variation of micro-scale redox environment of soil.
