Abstract

The aim of this study is to analyze the characteristics of the microstructure development in Latosols that originated from different parental materials and are located on the two main geomorphic surfaces of the Central Plateau. The analyses show several types of microgranular structure with different proportions but without any relationship with their texture and mineralogy. The study also shows that the microstructure would be related to bioturbation by termites mainly
