This trial was carried out at Selvíria county, State of Mato Grosso do Sul, Brazil, on allic, dark red, clayey latosol. The mean yearly is about 1,370 mm and temperature is 23.5oC. The rainfall goal was to evaluate the physical and chemical properties of a soil where corn and green manure were incorporated, with or without N fertilization (35 kg.ha-1) and their effects on wheat crop. The wheat positive response was greater with lab lab and velvet bean in single crop, but there was no response to N fertilization when the crop residues were incorporated to the soil. Physical and chemical properties of the soil were not affected by the treatments.
