Abstract

Copper is reported to be retained in soils for a quite long time particularly in soil treated with some amendments. This research was intended to evaluate the soil labile fractions of Cu ±10 years after application of Cu-containing industrial waste, lime, and cassava-leaf compost. Soil samples were taken from topsoils and subsoils of ±10 years old experimental plots set in 1998 and factorially treated with a metal-spoon industrial waste at 0, 15, and 60 ton ha-1, lime at 0 and 5 ton ha-1, and cassava-leaf compost at 0 and 5 ton ha-1. The measured Cu labile fractions were compared to those in soils sampled at ±1.5 years and ±3 years after treatments. The results showed that the soil Cu labile fractions in waste treated soils were higher than those in the control treatments even though their concentrations decreased with the years of sampling. Lime showed a decreasing effect on soil labile Cu fractions, but the effect decreased with the years of sampling. The effect of cassava-leaf compost application on soil labile Cu fraction was in general not evidenced ±10 years after treatment.
