The objectives of this research were to determine the forms of Cd, Cr, Ni, Pb, Cu and Zn in soils amended with sludge-municipal waste co-composts, and to correlate metal fractions with uptake by wheat and soybean under greenhouse conditions. A sequential extraction procedure was used to partition these metals into exchangeable/sorbed, organic, precipitated, and residual forms in the soil. As current regulations in Delaware require that soil pH be maintained at 6.5 when sludge-based materials are used, the influence of liming on plant uptake and distribution of the metals among these chemical fractions was also examined.
