The electrical measure of the soil has been used as variables that correlate with its characteristics. This study aimed to evaluate an electrical capacitance sensor of contact and verify the correlation between the measurements of electrical capacitance of the soil with properties sand, silt and clay. The data were submitted to the analysis of correlation and geostatistic. It were generated maps for each parameter of the soil surface through kriging technique. The purpose of the maps was assisting in the analysis of the correlation between the data. The electrical capacitance sensor was capable of measuring the variation of the electrical capacitance of the soil. The obtained measures were satisfactorily correlated with the levels of sand, silt and clay. This demonstrated the possibility of using a sensor to verify the soil texture in not homogeneous areas.
