| Popis: | The aim of the study was evaluate the physical-hydric properties of an ultisol cultivated with two eucalyptus hybrids, Urograndis and Grancam, irrigated and without irrigated. The experimental design was a randomized block in a split split plots, with 4 repetitions. In the plots, the treatments employed corresponded two irrigation systems (microsprinkler and drip) and without irrigation area. In subplot, treatments were the eucalyptus hybrids (Urograndis and Grancam) and the sub-subplots were the depths of soil of 0.0-0.1 m, 0.1-0.2 m, 0.2-0.3 m, 0.3-0.4 m and 0.4-0.5 m. Were evaluated the bulk density and soil porosity, soil penetration resistance and available water capacity for depths 0.0-0.5 m. The results were statistically analyzed by Tukey test to 5% probability. The irrigation (drip and microsprinkler) provides lowest soil penetration resistance in surface layer. Generally, the eucalyptus hybrids not influence in the soil attributes analyzed. |
