The need to rationalize the use of fertilizers and other chemicals, and financial resources has generated, increasingly, research in order to describe the spatial variability of soil properties in crops. This study aimed to study the spatial organization of soil properties in a wheat seed production field in an area of 11 ha. We collected four soil subsamples for chemical analysis and 10 samples for soil compression, using a 100 x 100 m grid. Descriptive and geostatistical analysis were performed to characterize the samples and identify the spatial dependence of the studied attributes. From the results obtained maps were drawn by “Agricultural System CR-Campeiro 7” software. The spatial organization of the evaluated attributes was heterogeneous. The chemical and physical attributes of the soil presented low or moderate spatial variability and moderate spatial dependence. The use of thematic map techniques can be used to optimize areas of wheat seed production.
