Abstract

In this study, the physical properties of a red latosol were assessed under Cerrado (a Savannah like vegetation type) and under of Eucalyptus grandis cultivation. Two contiguous sites of 14 ha each showing similar original vegetation cover, slope, topographic position, soil type, and sun exposure (aspect) were selected. Systematically, 20 sampling points were distributed in each site, from which soil deformed samples were collected to determine soil texture and non-deformed soil samples were collected to determine apparent density, volumetric soil moisture, and penetration resistance. Based on this study’s results, it was observed that by changing land cover of Cerrado vegetation to cultivation, E. grandis provided no significant changes, Scott-Knott test (α = 0.05) of soil penetration resistance, density, and volumetric moisture of the red latosol.

 

Key words: Cerrado vegetation, Eucalyptus grandis, land use, land cover change.
