The chemical and physical properties of a soil often show a spatial dependence. Thus, it is important to study their spatial variability, aiming to improve the crop management, to reduce the environmental impact, to optimize the machinery use, and to increase the efficiency of staff. So, this study aimed to evaluate the spatial variability of the physical properties of a distroferric Red Latosol (Typic Haplorthox) after soybean crop. The data were collected in an area of 2 ha managed under no tillage system, using a sampling grid of 30 x 33 m, where it was evaluated the macro, micro and the total porosity, the bulk density and the soil water content in 0 - 0.1 m layer. After the exploratory and geostatistical analyses, the theoretical models were set to the semivariograms for each attribute. The data interpolation was performed using the ordinary kriging. All the variables showed spatial dependence, which ranged from moderate (macroporosity, total porosity and soil water content) to strong (microporosity and bulk density), according to the nugget effect coefficient.
