With the objective to evaluate the spatial variability of the soil properties and coffee production in different geomorphic surfaces (GS) in the region of the high Paranaíba, MG, two regular grids of 200 x 850 m with intervals of 50 m were installed with 68 sampling points under coffee crop. The soil samples were collected at 0-0.20 m depth at the intersection points of these grids. The coffee production was evaluated in plants closer to the intersection of the grid point. Descriptive statistics and geostatistics analysis of the soil properties and production of coffee crop were performed. The chemical and textural properties of soil intensely managed possess dependence of the relief, even for small expression. The coffee production presented spatial dependence in both surfaces and largest variability in GS II. The limits between the geomorphic surfaces can represent limits of specific places of management.
