Resumo: Evaluations of dielectric constants E and samplings for the determination of ø and bulk density þm were carried out in four profiles of a Xanthic Ferralsol with high clay content (Latossolo Amarelao - Brazil Classification) at the Experimental Statation of Embrapa Amazonia Ocidental (Manaus, AM, Brazil). The sample were taken near the soil surface. Three undisturbed core samples and three disturbed auger samples were collected at each depth. The E was determined in advance at six points with the probe inserted vertically and three points horizontally in each depth. Results and discussion on: a) volume evaluated and probe orientation; b) topsoil and subsoil measurements; c) soil characteristics; and d) accuracy of empirical equations for the determination of soil wetness are presented.
