The application of industrial and municipal waste in the soil may be recommended by your corrective and fertilizer value, giving the great potential for agricultural reuse, improves physical, chemical and biological soil properties and helps to reduce the consumption of fertilizers and correctives, without contamination by heavy metals. This study aimed to evaluate the absorption of nutrients and potentially toxic elements, and their effect on the development of soybean (Glycine max (L.) Merrill) grown under No-Tillage system (NT). The work was developed in the field, at the Experimental Farm Lageado - FCA / UNESP, Botucatu (SP) in an Oxisol under tropical climate of altitude. The experimental design was randomized blocks, factorial 4x4+1, with four replications. The treatments consisted of four residues: two sewage sludge, one centrifuged and treated with quicklime (LC) and a biodigester (LB) and two industrial wastes: steel slag (E) and lime mud (Lcal) , applied in dosages of 0, 2, 4 and 8 Mg ha-1. The surface application of LC, LB, Lcal and E residues in soil under NT favored the development of soybean, with no heavy metal contamination, given the current legislation.
