Adsorption kinetic and cadmium fractions in two calcareous soils affected by zinc and different moisture regimes

This study has been conducted to ascertain the impact of zinc (Zn) on cadmium (Cd) fractions in two types of calcareous soils of the Fars Province in Iran at the waterlogged and field capacity conditions; also we investigated the adsorption of Cd in soils throughout different shaking times. We examined the effect of Zn on Cd fractions due to their similar characteristics. Treatments were three levels of Cd (0, 30 and 60 mg kg−1 of soil as...
