Abstract

On Reunion, the AA. undertook an overview of the old existing soil studies. This paper describes (1) the procedure used to update the soil maps and the toposequence acquired with the old French Commission de Pédologie et de Cartographie des Sols (CPCS) classification system, without any new information, using the World Reference Base for soil resources (WRB); (2) the construction of a new soil map drawn up with completely new information, and (3) a comparison of these 2 approaches. Without any new information, incorrect updates were observed for both the determination of Reference Soil Group (RSG) and the qualifiers. Despite the field descriptions, the lack of any analytical determinations on the old soil studies was a source of updating errors for the more developed soils formerly qualified as ferrallitic. In order to update limits for Andic properties and Andosols, the systematic use of analytical determinations has to be considered for updating old soil maps, as the diagnostic criteria are more restrictive than in the past
