The soil bulk density of undisturbed samples was evaluated using computed tomography and paraffin-sealed soil clod techniques, with the objective of identifying soil compaction processes and to compare the applied methodologies. Data were also used to complement a soil classification survey for irrigation purposes. Samples were collected from soil profiles of the semi-arid region of Petrolina (PE), Brazil, from the soil surface down to a depth of 1 m, in 10 cm layers. Two distinct areas were chosen: (1) native […]
