This experiment aimed to analyze changes in spatial behavior of the attributes of soil: clay dispersed in water (CDW), degree of flocculation (DF) and organic matter (OM) in areas occupied by native vegetation in natural regeneration and pasture. Soil samples were collected at a depth of 0.0-0.2 m in a grid with 64 sampling points, spaced at 10 m. The data were submitted to descriptive and geostatistics analysis. The highest values were observed for the CDW and the lowest values of DF in the pasture. All attributes show spatial dependence for the two areas of study, with adjustment of the spherical and exponential models. The preparation of thematic maps using the ordinary kriging allowed better visualization of the spatial variability of soil attributes.
