【 摘 要 】

This work aimed to access the contents and chemical forms and to estimate mobility and availability of cooper and zinc in samples from two soils (Haplortox and Paleudult) previously treated with doses of sewage sludge (SS) and municipal solid waste compost (MSWC), besides a control treatment. Largest percentages of Cu and Zn were determined in the organic matter fraction. Zn showed higher percentages of soluble and exchangeable fractions than Cu. Treatments with SS showed higher potential of Cu and Zn availability. Modifications in soil attributes due to residue application affected metal mobility and availability indexes.
