Abstract: Intensively and inadequately managed soils and the civil construction industry in the rural area that are unconcerned with specific legislation, result in several problems in the environment. The objective of the present study was to evaluate the influence of sewage sludge on the recovery of hydro-physical properties of an Oxisol. The experiment was implanted in 2004, in Selvíria, Mato Grosso do Sul, Brazil. The six experimental treatments were arranged according to a randomized complete-block design with four replications. The experimental treatments were: 1 - Native Cerrado vegetation; 2 - degraded soil without treatment for soil recovery; 3 - Eucalyptus citriodora planting and Brachiaria decumbens sowing and no sewage sludge or mineral fertilization use; 4 - Eucalyptus citriodora planting and Brachiaria decumbens sowing in soil enriched with mineral fertilizer; 5 - Eucalyptus citriodora planting and Brachiaria decumbens sowing in soil enriched with 30Mg ha-1 sewage sludge, and 6- Eucalyptus citriodora planting and Brachiaria decumbens sowing in soil enriched with 60Mg ha-1 sewage sludge. Hydro-physical properties and the soil organic matter content were characterized at 0.00-to-0.05; 0.05-to-0.10; 0.10-to-0.20 and 0.20-to-0.30m layers in the soil. Mineral and organic fertilization treatments showed similar effects on the recovery of the hydro-physical properties and organic matter content of the degraded soil. The hydro-physical properties and organic matter content of Cerrado soils degraded due to civil construction activities can be recovered by the use of 30 to 60Mg sewage sludge ha-1.
