The main objectives of this paper were (1) to determine soil bulk density of undisturbed samples, using both conventional and computed tomography (C.T.) techniques to identify soil compaction processes and (2) to compare the two methodologies. Soil samples were collected in a semi-arid region of Petrolina, PE, Brazil, along the soil profile, in O.1 m steps down to 1 m depth, at two sites: 1. Soil under natural vegetation "caatinga", and 2. Cultivated soil irrigated by central pivot. Soil C.T. scanning was performed with a first generation C.T. scanner and the conventional method was the gravimetric method (mass and volume measurement of the sealed clods). Results suggest that there is a natural soil compaction in deeper layers, and for the pivot irrigated area, the presence of man induced compacted layer, between 0 and 0.4 m. The comparison of the methods presented soil buk density values of satisfactory coincidence. |
