Conteúdo:	Nature of the system; diagnostic horizons and diagnostic properties; soil classes and their definitions; correlation between soil classes of Brazilian-SNLCS, FAO and Soil Taxonomy systems. Brazilian soil science is in its infancy. In studies before 1947 soils were mainly classified in relation to parent material or geomorphological units. In 1947 a national soil science society and survey institution were founded. A programme of reconnaissance soil surveys of Brazil started with the survey of the state of Rio de Janeiro in 1954. At present the entire country has been mapped at the exploratory level, with about 20% at exploratory-reconnaissance level, plus 15% at reconnaissance level and a rather small percentage at more detailed levels.
