【 摘 要 】

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