Cadmium in plants and soil

The amount of cadmium in soils is generally low but once it has been added to the soil, it can take between 100 and 1000 years for the levels to drop by 50%. When cadmium is present in soil, it is more available to plants if the soil is sandy, acidic or low in organic matter. [2]
