Abstract in Portuguese
O presente trabalho teve por finalidade o estudo de cutans em dois perfis de solos da série Iracema pertencente ao grande grupo Latossol Roxo e em dois perfis de Terra Roxa Estruturada. Tal estudo teve como base o exame das amostras dos perfis em secções delgadas, examinadas sob microscópio petrográfico. O exame de uma boa quantidade de lâminas revelou a presença de cutans iluviais nos horizontes B21 dos Latossóis Roxos, no horizonte B1 e parte do B21 do perfil P3 (Terra Roxa Estruturada) e nos horizontes B21 e B22 do perfil P4 (Terra Roxa Estruturada). A par ao estudo das cutans desenvolveu-se pesquisa acerca de um bom material impregnante e de fácil aquisição para as nossas condições, concluindo-se que, a resina poliéster Polylite T 213 convenientemente preparada, é um excelente material para esse fim.
Abstract in English
The purpose of this work was the study of cutans in two soil profiles of the Iracema series, Roxo Latosol 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 oriented 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 horizon of the Roxos Latosols, (profiles P1 and P2), in the B1 and part of the B21 horizons of profile P3 (Terra Roxa Estruturada) and in the B21 and B22 horizons of profile P4 (Terra Roxa Estruturada). Research was also conducted on the performance of various impregnating materials. It was concluded that the polyester resin, Polylite T 213 is an excellent material for this purpose.
