Changes in soil soluble Zn of metal-spoon industrial waste were evaluated in tropical soils under lime and/or cassava-leaf composts treatments. Soil samples from Gedongmeneng and Banjaragung (Lampung) and Cihea (Cianjur, West Java) were used as models. Soil samples were incubated for 4 weeks at 40 percent moisture contents and room temperature after through treatments with metal-spoon industrial waste at 0-40 ton/ha and/or CaCO3 at 0-5 ton/ha and/or cassava-leaf composts at 0-10 ton/ha. Unlike Cu, the soluble Zn increased with addition of industrial waste at 10 ton/ha and decreased with addition of higher rates in order of 10 20 40 0 ton/ha. Lime increased the soluble Zn of industrial waste origin and cassava leaf composts showed no effect. Soil of Banjaragung showed a greater immobilization capacity with respect to Zn than soils of Cihea and Gedongmeneng
