Abstract

From a study of the distribution of the total trace-element content of 18 profiles in Cameroun, belonging to 6 different classes, the following conclusions have been reached: 1. (1) The zone of influence of the parent material is constituted by the weathering horizons (BC and C). 2. (2) The zone of influence of the pedogenetic factors is constituted by the horizons of the “solum” (A and B). 3. (3) Each soil-type exhibits its own geochemical character which may be expressed as the sum of the total content of trace elements with the same physico-chemical behavior. The results of quantitative spectrographic analyses of the 14 most common trace elements as observations on the pedogenetic factors which may be responsible for their distribution have been set out in four profiles: a ferralitic red soil; a ferruginous tropical soil; a brown soil; and a planosol.
