ABSTRACT The original landscape of Campos de Cima da Serra region has changed by anthropogenic interference. The study aimed to evaluate soil chemical and physical attributes of an Oxisol under natural grassland (CN), burned natural grassland (CNq), natural forest (MN), pine afforestation (PF)and annual crops in conventional tillage system (LA), in the 0. 00-0.025, 0.025-0.05, 0.05-0.10, 0.10-0.20, 0.20-0.30m layers. The mineralogy was evaluated by X-ray diffraction. It was evaluated the total organic carbon (TOC); pH (H
