                         Penetrating Radar) in detection of compacted soil layers, as well 
                         the possibility of application in studies of subsurface research. 
                         The searches were carried out in two areas used for several years 
                         with the sugar cane growing, which have received the same 
                         management over time. Soil samples were obtained with volumetric 
                         cylinder in depths of 0-0,10 m, 0.10-0.20 m; 0.20-0.30 m; 
                         0,30-0,40 m 0.40 at 0,50 meters over three transept by area, one 
                         referring to the lines and two lines. The results obtained were 
                         applied to semi-empirical equation of Crim for obtaining the 
                         possible outcome that would be determined by geophysical GPR. The 
                         values generated by georadar for the two areas had to be close of 
                         those obtained by the Crim equation for the treatments, when 
                         considering the package of ground to the range of 0.40 to 0.50 
                         meters. However, the more superficial layers of soil could not be 
                         assessed due to technical limitations of equipment associated 
                         physical and chemical conditions of soil, which undermined the 
                         reflections. The GPR was able to detect density differences in the 
                         profile, when confronted with between rows, but it was not 
                         possible to determine which would be compacted layers. The results 
                         showed that the radar can be effective in some soil studies when 
                         combined with other methods, but alone this technique needs 
                         further studies in addition to improvements by the equipment.",
