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 treatments with 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 ±1.5 years and ±3 years after treatments. The results showed that the soil Cu labile fractions in waste treated soil were higher than those in the control treatments even though their concentration 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. Effect of cassava-leaf compost was in general not observed ±10 years after treatment.
