چکیده انگلیسی
We conducted a pot experiment to evaluate the effect of soil washing with CaCl2 on Cd absorption by two soybean cultivars. The results were as follows: (1) Soybean growth was not significantly different in washed and unwashed soils, but the seed Cd concentration for both cultivars decreased significantly, up to 25%, in the washed soils compared with the unwashed soils. (2) In the washed soils, the Cd concentration in the soil solution indicated an obviously lower value from sowing to the flowering stage; however, the change in Cd speciation was not evident in the CaCl2-washed soil solution. Consequently, the effect of soil washing using CaCl2 on Cd-contaminated paddy soils can be expected to continue after a CaCl2-washed paddy field is converted to an upland field.
