Abstract

Lime and/or organic compost are suggested to lower the solubilities of heavy metals in soil systems. This research was to study the changes in copper and zinc solubilities in an Andisol from Lampung. Soil sample was collected from Ap horizon of Gisting, Tanggamus, Lampung. The soil sample was spiked with a model waste (a mixture of standard solutions containing Cu and Zn) or treated with industrial waste high in Cu and Zn. At the same time, the soil sample was also treated with lime at rates ranging from O to 10 ton ha-1 and/or cassava-leaf compost at rates ranging from Oto 20 ton ha-1. The soil mixture was then analyzed after a-4 week incubation at 40% moisture content. The results showed that the soil pH increased with the increase in lime and/or compost additions. The industrial waste also showed a liming effect by increasing the soil pH. Unlike those shown by similar experiments with other soil orders, the solubilities of copper and zinc in the Andisol increased with the increase in lime and or compost addition. The addition of the model waste or the industrial waste did not alter this trend except that the concentrations of Cu and Zn in soils treated with industrial waste were much higher.
