From digital soil mapping to digital soil assessment: identifying key gaps from fields to continents: proceedings... Rome: IUSSc2010  aThe development of methods in digital soil mapping has been an activity that's growing substantially in recent decades. The DSM is quickly evolving from the research stage to map production at various scales covering countries, regions and river basins (Lagacherie and McBratney, 2007). The prediction of classes and properties of soils in digital mapping is based on the relationship between the factors and soil formation processes. Chemical knowledge of soil attributes is a factor of great relevance for rational use of limes and fertilizers. This work’s study area are the regions: north, northwest and Serrana do Estado do Rio de Janeiro.  aDevelopment of methods  aDigital soil mapping  aStudy area1 aMENDONÇA-SANTOS, M. de L.1 aCARVALHO, C.
