dc.descriptionThis work aimed to use a GPR equipped with a 450 MHz antenna to identify the depth of the clayey horizon marked with iron rods in Planosols. This study was carried out in an agroecological farm (Fazendinha Agroecológica do km 47), located in Seropédica municipality, Rio de Janeiro state, Brazil. First, three Planosols were described, and iron rods with dimensions of 80 cm in length and 0.8 cm in diameter were inserted in the transitions among soil horizons. Next, radargrams from the soil profiles and from one transect with those profiles were acquired using a GPR porting a shielded monostatic antenna of 450 MHz. Then, a depth model was adjusted to the transect radargram using the arithmetic average from the pulse velocities measured among the individual radargrams from the soil profiles. As the result, the average velocity created a depth model for the transect radargram that produced similar depths to those transitions viewed in the field for the argillic horizon.
