RICCI, Alexandro Batista; PADOVANI, Vera Cristina Ramalho  e  PAULA JUNIOR, Durval Rodrigues de. Use of stabilized sewage sludge on a humusless soil: I - physical properties and revegetation. Rev. Bras. Ciênc. Solo [online]. 2010, vol.34, n.2, pp.535-542. ISSN 1806-9657.  http://dx.doi.org/10.1590/S0100-06832010000200027.

The application of treated and stabilized sewage sludge to soils has been shown to be a viable disposal alternative, since costs are low and cause no negative impacts, but contribute to the restoration of the original characteristics of some degraded soils. This experiment was carried out in Mogi Guaçu, State of São Paulo (Brazil) to evaluate the effect of doses (0, 20, 40, and 80 Mg ha-1) of an organic compost of sewage sludge and grass residues on the recovery of a humusless soil, in particular on the soil physical properties and revegetation with native species. It was found that doses of sewage sludge compost did not change the soil physical properties at the site under study and the plant height and diameter of the chosen reforestation species were not influenced by increasing doses of sewage sludge compost applied to humusless soil, regardless of the succession group.

Palavras-chave : Solid residues; reforestation; degraded soil.
