Effect of Composting on the Cu Speciation in Cow-Based Compost Using BCR Sequential Extraction

Abstract— Compost derived from cow-based manure mixed with agricultural waste was studied for four Cu fractions: exchangeable fraction (Cu-Ex), oxide-bound fraction (Cu-Ox), organically-bound fraction (Cu-Org), and residual fraction (Cu-Res). Cu-Res was found the most for entire process of composting within the range of 68.6-97.1% following by Cu-Org, Cu-Ex, and Cu-Ox indicating the high preference of more stable forms. As the organic matters were decomposed, the mobility of Cu increased corresponding with time (p<0.01) especially after reaching mature stage at day 35. Thus, composting process helped to increase the amounts of Cu. Nevertheless, using the compost to the field still needed to consider other characteristics, such as organic matter and other nutrients which should not be depleted by microorganism under too long composting.

Index Terms— Compost, BCR, Sequential extraction, Cu.
