Abstract

The purpose of this work was the study of cutans in two soil profiles of the Iracema series, Latossol Roxo Great Group, and two profiles of Terra Roxa Estruturada.] The study was based on the exam, under the petrographic microscope, of thin sections prepared from undisturbed soil samples taken from the main horizons of the four profiles under study. The exam of the thin sections revealed the presence of illuvial cutans in the B21 horizons of the Latossol Roxo (profiles P1 and P2), in the B1 and part of the B21 horizons of profile P3 (Terra Roxa Estruturada) and int the B21 and B22 horizons of profile P4 (Terra Roxa Estruturada).
