Abstract
Heavy metals are suggested to influence the growth of crop plants. This research was intended to evaluate glasshouse growth of corn in potted soils treated with industrial waste containing heavy metals. Soil samples (from Banjaragung and Gcdongmeneng Lampung) were thoroughly mixed with a metal-spoon industrial waste containing high amounts of Cu and Zn at 0, 20, and 80 ton ha-1or a model waste to increase soil heavy metals (Cu, Zn. Cd. and Pb) 10 and 40 mg kg-1. All treatments were also factorially treated with lime at 0, 2.5, and 5 ton CaCO3 and/or cassava-leaf compost at 0, 5, and 10 ton ha-1 and cultured to corn for 4 weeks. The growth of corn plant was significantly inhibited by heavy metals of high level model waste. The negative effect of high level model waste in Banjaragung and Gedongmeneng soil was alleviated by addition of lime and/or cassava-leaf compost. On the contrary, similar to that of the low level model waste, the industrial waste addition stimulated the growth of com in Banjaragung soil. This positive effect in general lessened with lime addition, most probably due to the increase in Zn solubility with increasing soil pH. These phenomena were not observed in Gedongmeneng soil.
