Abstract

Being toxic to biota, heavy metals are suggested to inhibit plant growth. This research was to evaluate com growth and yield in soil amended with heavy-metal-containing waste under field conditions. Field plots (of Ultisols in Sidosari, Natar, South Lampung) were factorially treated with lime at O and 5 ton CaC03 ha-1 and cassava-leaf compost at O and 5 ton ha-1 one week after waste treatment at 0, 15, and 60 ton ha-1, after which corn seeds were planted. Waste addition gave no effect on plant height, but it increased plant height when cassava-leaf compost and lime were also added. Waste addition decreased plant yield and so did lime and compost additions. However, plant yield increased with waste addition when soil was also treated with lime. This phenomenon was directly related to the decrease in soil available Cu with the increase in soil pH by lime addition, particularly when industrial waste was added at 15 ton ha-1.
