This article presents a revision of the abstracts of The XX Brazilian Meeting of Fertility of the Soil and Nutrition of Plants, realizado in Piracicaba-São Paulo. The agronomic use of residues pressuposes a diverse number of applications such as their use in: animal feeding, substrate for fermentations, organic or organo-mineral fertilizer manufacture, soil coverages in different creations and substitutes of raw material for the agroindustrial or similar activities. However, the objective of this presentation is restricted to the aspects of the use of residues in the soil, understanding the aspects related to the characterization of these residues, the benefits or inconveniences of the application to the soil and the parameters that must be observed when the intention is to give this destination to the residues. In this way, this subject can be divided in two basic aspects: the residues and the soils. Concerning the residues, the main factors that affect their application to the soil are: chemical composition, physical characteristics, sanitary aspects, generated amount and regimen of release. In relation to soil, we must consider all those characteristics which are responsible for the capacity of the soil in deactivating and stabilizing the residues, through physical chemical and biological mechanisms. It is in this general framework that we intend to approach some specific aspects which are considered more important for the use of residues in soil.
