There is lack of research on Argissolos (Ultisols and Alfisols) in relation to theunderstanding of the pedologic variations. Variations can be analyzed by multivariate statisticsand the data numerically classified. The comparison between the numeric classification andthe hierarchical classification can contribute to the evolution of the Brazilian Soil ClassificationSystem (SiBCS). The aims of this research were to analyze the pedologic variation of Argissolosderived from sedimentary materials in the central region of Rio Grande do Sul and to validatethe organization of the […]
