Teste de sensores no perfil de um solo arenoso.

Abstract

Currently, to monitor the tensions in the soil is possible, by means of sensors that can inform the level of compacting in the profile of the soil Santos Filho,(2003). By means of the necessity of bigger studies in this area, the present work had for objective to evaluate the instrumented blad Sensory Profile, developed for Andrade et al. (2001) for measurement the forces in the profile of the sandy soil, dry, verifying the capacity of identification of the compact layers. For such, in field conditions, in dry soil with 5%, using the Sensor Profile, under the speed 0,67 m/s, a Strata Gauge for determination of the moister content and density of the soil and on Hydraulic Penetrometer to measure the resistance the penetration in the soil. As result of the research, it is concluded that the sensors presented consistency of data, when compared the techniques of inquiry of the compact layers in the soil profile, for the traditional methods.
