Abstract
Cation retention by soil colloid adsorptive surfaces is believed to inhibit the movement of heavy metal cations in soils. This research was to investigate the movement of Cu and Zn in cultivated field-plots 3 years after treatment with an industrial waste containing considerable Cu and Zn, lime, and organic compost. Three levels of industrial waste (0, 15, and 60 ton ha-1) were mixed with field topsoils of 0-15 cm one week after treatment with lime and organic compost. Extracted Cu and Zn were measured in soil samples collected depth-wise from 0 to 75 cm in field-plots 3 years after treatments. Copper and Zn only from high-level waste-treatments were observed to have significantly moved from topsoils to subsoils of 30 – 75 cm. Unlike that of Zn, the movement of Cu was also shown to be significantly lowered by topsoil treatment with lime and/or compost, suggesting that the increase in soil adsorption capacity inhibited the movement of Cu cations. Most Cu and Zn were retained in topsoils.
