Abstract: The disposal of sewage sludge and other organic waste on the soil seems be an alternative for the public sector since this can provide nutrients for the growth and maintenance of plant species that constitute the urban systems of green areas. This experiment was conducted in Mogi Guacu, State of Sao Paulo to evaluate the effect of doses (0, 20, 40 and SO Mg ha(-1)) of an organic sewage sludge coin post and grass residue on the recovery of a humusless soil, particularly on the soil chemical properties and revegetation with native species. At a dose of 80 Mg ha(-1) sewage sludge compost an increase was observed in the level of P, Ca, Mg, K, Mg, Fe, and soil pH, with. positive influence on fertility and Unaltered soil organic C content. The index of soil cover by tree canopies was not influenced by increasing doses of sewage sludge compost on humusless soil.
