Control of heavy metal movements in soil bodies is important to minimize ground-water contamination. This research was to evaluate effects of lime and/or cassava-leaf compost on changes in heavy metal.solubilities along columns of tropical .soils continuously leached with water. Soil samples were collected from Tanjungan (South Lampung) and Banjaragung (Central Lampung, Indonesia). Soil samples were thoroughly mixed with CaCO3 at O or 5 ton ha-1 and/or cassava-leaf compost at O or 10 ton ha-1. In addition to the control treatments (without Cu and Cd addition), experiments were also conducted with model waste (containing standard Cu and Cd) and metal-spoon industial waste. Leaching was conducted at a rate of 20% of the soils' dry-weight every 2 days for 30 days. Lime and/or cassava-leaf compost were found to increase soil pH and decrease the solubilities of Cu and Cd in soils. Water leaching showed no effects on soil pH along soil columns. Copper and Cd solubilities in all soil layers generally increased after leaching. Translocation of Cu and Cd along the soil columns were miniscule.
