| The association between the mineralogy of the clay fraction, the structure and the physico-hydraulic behavior of the Brazilian Latosols (Oxisols) is addressed here in a global, simple, objective, and instructive context. The simplicity of the mineralogical composition of the clay fraction of Latosols facilitates the understanding of cause and effect relationships in this context. Higher kaolinite contents favor the manifestation of the blocky structure, resulting in higher bulk density values, lower water infiltration rates, and lower potential aquifer recharge. Conversely, higher levels of gibbsite and Fe-oxide minerals (mainly hematite and goethite), in this order, favor the small granular structure of high stability in the subsurface horizon (B) of the... |
