Abstract

The growth of amaranth under field conditions in soils polluted with Cu- and Zn-containing industrial waste was evaluated in 1998 in Sidosari, Natar; South Lampung, and in Sri Bawono, Central Lampung. Soils were factorially treated to 0-to-l5-cm depth with lime (at O and 5 ton CaCO3 ha-1) and cassava-leaf compost (at O and 5 ton ha-1). A metal-spoon industrial waste containing Cu and Zn (at 0, 15, and 60 ton ha-1) was also given to the same depth in the subsequent week. One week after waste treatment, soils were cultured to amaranth for 5 weeks. The available Cu and Zn in soils significantly increased with waste levels, but only at 15 ton. waste ha-1lime and/or cassava-leaf compost decreased the available Cu and Zn. The changes in the available Cu and Zn by lime and/or compost additions in general showed no correlation with the growth of amaranth. However, the growth of amaranth in Sidosari was depressed by the increasing waste addition, indicating the negative effect of heavy metal inputs from waste. The growth of amaranth in Sri Bawono was also depressed, but, different from that in Sidosari, lime and cassava-leaf compost significantly alleviated this negative effect.
