Boundary between Soil and Saprolite in Alisols in the South of Brazil Rev. Bras. Ciênc. Solo
Pedron,Fabrício de Araújo; Oliveira,Rodrigo Bomicieli de; Dalmolin,Ricardo Simão Diniz; Azevedo,Antonio Carlos de; Kilca,Ricardo Vargas.
Despite numerous studies conducted on the lower limit of soil and its contact with saprolite layers, a great deal of work is left to standardize identification and annotation of these variables in the field. In shallow soils, the appropriately noting these limits or contacts is essential for determining their behavior and potential use. The aims of this study were to identify and define the field contact and/or transition zone between soil and saprolite in profiles of an Alisol derived from fine sandstone and siltstone/claystone in subtropical southern Brazil and to subsequently validate the field observations through a multivariate analysis of laboratory analytical data. In the six Alisol profiles evaluated, the sequence of horizons found was A, Bt, C,...
