CENTURION, José Frederico; BEUTLER, Amauri Nelson  and  SOUZA, Zigomar Menezes de. Physical attributes of kaolinitic and oxidic oxisols resulting from different usage systems. Braz. arch. biol. technol. [online]. 2004, vol.47, n.5, pp.725-732. ISSN 1516-8913.

The objective of this study was to assess the physical attributes of a kaolinitic oxisol, medium texture (Haplustox) and an oxidic oxisol, clayey (Eutrustox) under different usage systems, localized in the region of Jaboticabal, SP, Brazil. The usage systems were sugarcane, cotton and forest. Parameters such as soil bulk density, total porosity, macro and microporosity at the depths of 0.0-0.1; 0.1-0.2; 0.2-0.3, and 0.3-0.4 m were evaluated. Haplustox showed greater bulk density and smaller total porosity, macro and microporosity. The usage increased the bulk density in 0.0-0.3 m depth, with greater effects on the kaolinitic oxisol, mainly in 0.1-0.2 m depth in the areas cultivated with sugarcane.

Keywords : Sugarcane; cotton; forest; mineralogy; porosity; bulk density.
