Abstract A study on vertical transport of aqueous Zinc (Zn) and Cadmium (Cd) in soil system has been carried out at the soil science laboratory of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal, India. Aqueous solution of Zn and Cd are vertically leached down through the soils collected from Pundibari (Agroecological zone 15.1, climate: sub-humid) and Malda (Agroecoloogical zone 15.1, climate: sub-tropical humid) in a double-chambered glass column. The similar procedure has been repeated for the soils collected from both places separately mixing with farm yard manure. The formation of the Breakthrough Curves (BTCs) for Zinc in Pundibari soils at 0.97 pore volume (Pv), while at 0.85 (Pv) in soil treated with FYM. The BTCs for Malda was at 0.49 (Pv), and that in soils treated with FYM was at 0.36 (Pv), while the BTCs for Cadmium at 0.96 (Pv) for Pundibari soil and that at 0.83 (Pv) for soil treated with FYM were observed. The order of time of dilution in both the cases using Zinc and Cadmium solution in the leachate followed as: Malda (Soil+FYM) > Pundibari (Soil+FYM) > Malda (Soil) > Pundibari (Soil) respectively. The capacity of soil mixed with FYM was found to be an effective sink for metals like Zinc and Cadmium and thus moderating the toxic effects of Zn and Cd in soils.
