Cadmium and cadmium compounds are water soluble, mobile in most soils, bioavailable,
and tend to bio-accumulate. A pot culture experiment was conducted on
contaminated soil to study the influence of lime and organic matter on the mobility
of cadmium in spinach and its rhizosphere soil. Application of lime (50% and 100%
lime requirement) and organic matter (0.5 and 1% by weight of soil) to soil decreased
the availability of Cd to the soil and plant throughout the crop growth. The highest
diethylene triamine penta-acetic acid (DTPA) extractable Cd was 10.84 mg kg−1 in the
treatment OM0 L0 (No application of organic matter and lime) at 20 days after sowing of
spinach. Likewise, the highest Cd concentration in spinach roots and shoots were 19.80
and 17.0 mg kg−1 in the treatment OM0 L0 at 20 days after sowing. The Cd concentration
in spinach roots and shoots were decreased by 63.23 and 71.88%, respectively, in the
treatment OM1 L100 (application of FYM at 1.0% by weight of soil and lime at 100%
lime requirement) after 60 days of growth. The lowest concentrations of Cd in the soil
and plant after the harvest of the crop were 2.88 and 4.27 mg kg−1, respectively, in the
treatment OM1 L100 and resulted in 65.75 and 71.55% decrease over control (OM0 L0).
The highest total chlorophyll content of leaves was 2.19 mg kg−1 of fresh weight in the
treatment OM1 L100 at 40 days of crop growth.
