Describing the soil properties spatial pattern allows the study of spatial distribution of these variables. Geostatistics tools are necessary on this process, allowing the spatial dependences analysis. The objectives of this work were: describe the spatial variability of soil water storage and the relationship between soil water storage and crop yield. The experimental area were sub-divided on 80 squares, with 9 m each one. The variables studied were collected in each point, allowing geostatistics analysis. The results showed that the studied variable presented structure of spatial dependence. The spatial distribution of soil water storage was shown to be strongly stable in time, being dictated mainly by intrinsic factors of soil and little influenced by the uniformity characteristics of the water application. The negative spatial correlation between water storage and crop yield showed that the aeration could be the main problem of this system. keywords: spatial distribution, geostatistics, water storage.
