The technique of temporal stability is used by several researchers to adequately represent the water content in the soil with reduced sampling effort from the identification of points on the field that reflects the average behavior of soil moisture. Therefore, the aim of this work was to analyze the moisture behavior to the spatial variation of density and particle size in a Hapludox under three different soil tillage systems (No-Till, Crop-Livestock Integration and Conventional Planting) in the municipality of Jataí, Southwest of Goias, Brazil. It was collected nine sampling points information for each handling system in three depth ranges (0 - 0.12 m, 0.12 to 0.24 m, 0.24 to 0.36 m). For this, it was used a portable type sensor TDR HydroSence model, rods with length 0.12 m. The determination and location of points for data collection were done by georeferencing, using a GPS system ("Global Positioning System"), GARMIN, MAP785 model. Bulk density and soil particle size (clay) were determinated according to the recommendation by EMBRAPA. The experimental area was composed of three sub-areas of approximately 1 ha each, cultivated with soybean (Glycine max) in the season 2013/2014 (first crop) with different soil management systems. Statistical analyzes were performed using analysis of variance and Pearson correction. The spatial variation was represented using the SURFER software. The results of variance analysis indicate statistical differences between values of bulk density and soil particle size between depths, between the different management and spatial distribution within each management. It was perceived spatial relationship between moisture and attributes studied for some depths and types of management, but there was little influence of physical attributes in the behavior of moisture to the soil and conditions studied.
