The objective of this study was to evaluate the physical-hydric properties of a Planosol under an Integrated Crop-Livestock-Forest (ICLF) system in the Agreste region of Para & iacute;ba, Brazil, after eight years of implementation, and to compare them with areas under a conventional cropping system and secondary native vegetation. The experiment was conducted at the experimental station located in Alagoinha, in the Agreste mesoregion of the State of Para & iacute;ba, Brazil. The experimental design adopted was a randomized block design (RBD) with five treatments and four replications (5 x 4 + 2). The treatments consisted of: (1) Gliricidia (Gliricidia sepium (Jacq.) Steud) + Signal grass (Urochloa decumbens) (GL+SG); (2) Sabi & aacute; (Mimosa caesalpiniaefolia Benth) + Signal grass (SB+SG); (3) Purple Ip & ecirc; (Handroanthus avellanedae (Lorentz ex Griseb.) Mattos) + SG (I+SG); (4) annual crop + SG (C+SG); and (5) Signal grass (SG). Two additional treatments were included for statistical comparison: a conventional cropping system (CC) and a secondary native vegetation area (NV), both located near the experimental site. The CC treatment showed the lowest bulk density (1.23 g cm(-3)) and the lowest degree of compaction (66.3%) among the evaluated treatments, as well as a total porosity (TP) higher than 75% (0.75 m(3) m(-3)). In the soil under the integration system, the lowest bulk density (1.38 g cm(-3)) and the highest total porosity (0.48 m(3) m(-3)) were observed in the SG treatment at the 0.0-0.10 m depth. High S-index values (>0.035) and a low relative field capacity (RFc < 0.50) and K-theta indicate high structural quality and low soil water storage capacity. It was concluded that the SG, I+SG, SB+SG, and CC treatments presented the highest values of soil bulk and degree of compaction in the layers below 0.10 m. The I+SG and C+SG treatments showed the lowest hydraulic conductivities and macroaggregation. The SG and C+SG treatments had the lowest available water content and available water capacity across the three analyzed soil layers.
