Heavy metal accumulation is known to be detrimental to animal and human health. This research was to investigate role of lime and/or cassava-leaf compost in lowering Cu and Zn absorption by crop plants. Soil sample (Alfisol) was thoroughly treated with Cu and Zn standard solution at 0, 10, and 40 mg kg-1 or metal-spoon industrial waste at 20 and 8O ton ha-1 and factorially treated with lime at 0-5 ton CaCO3 ha-1 and cassava-leaf compost at 20 and 8O ton ha-1. After a 1 week incubation at 40% moisture content, soil mixtures were cultured to amaranth or corn for 4 weeks in a glasshouse, after which Cu and Zn accumulation in plant roots and shoots was analyzed by graphite furnace AAS. Copper concentration of standard solution or industrial waste origin in amaranth was higher than that in corn shoots and decreased with liming and/or cassava-leaf compost addition. Liming and/or cassava-leaf compost also decreased the Zn concentration in amaranth shoots at high level standard Zn addition but increased the Zn concentration at low level standard Zn addition. Conversely, liming increased and cassava-leaf' compost decreased the Zn concentration in amaranth shoot cultured in waste treated soil. Effect of lime and cassava-leaf-compost on Cu and Zn concentrations in corn shoots showed no clear pattern.
