Resumo: | 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 in Lavras do Sul, RS, Brazil. Collecting soil four subsamples for chemical analysis and 10 for compression using a 100m X 100m grid by sampling was performed. Descriptive analysis and geostatistical was 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 greater variability checked by coefficient of variation was observed for the phosphorus content, the other had medium and low variability. All attributes have moderate spatial dependence and range equal to or above the maximum search radius.
