Knowledge about the physical and hydric characterization in the soil is essential for studies on land use and plant development. Thus, this study evaluated water retention and its interrelationships with the physical and chemical attributes of Cambisols under different land uses in a rural settlement in a semiarid region of Brazil. The analysis of soil water retention curves associated with multivariate statistics was performed to distinguish agroecosystems. The environments studied were Preserved Forest - reference area, Cajarana Orchard Area, Corn/Bean Consortium, Watermelon/Pumpkin Consortium, and Agroecological Cultivation. It was obtained as a result that Preserved Forest presented the highest field capacity, permanent wilting point, and available water. However, there was greater water retention in Cajarana Orchard Area compared to other environments. The reference area and Agroecological Cultivation maintained conditions that improve the soil structure, weighted mean diameter, microporosity, and total porosity. In Watermelon/Pumpkin Consortium and Agroecological Cultivation, there was a greater contribution of the organic total carbon contents and in Cajarana Orchard Area, and Watermelon/Pumpkin Consortium had discriminating variables the clay, hydrogenionic potential in water, and macroporosity. Thus, the multivariate analysis allowed to analyze changes in water retention, which differed not only between land use but also in-depth and inorganic soil fractions. In addition, it was concluded that the soil tillage systems alter the chemical, physical and structural attributes of Cambisols of the semiarid studied and that the minimum tillage is an alternative to be adopted as the most suitable for the region.

关于土壤的物理和水合特性的知识对于研究土地利用和植物发育至关重要。因此，本研究评估了巴西半干旱地区农村居民点在不同土地利用下的保水量及其与坎比索的物理和化学属性的相互关系。进行了与多元统计相关的土壤保水曲线分析，以区分农业生态系统。所研究的环境为：保护森林-参考区，卡贾拉纳果园区，玉米/豆类财团，西瓜/南瓜财团和农业生态耕种。结果表明，保鲜林具有最高的田间持水量，永久性枯萎点和可用水量。然而，与其他环境相比，卡哈拉那果园地区的保水能力更高。参考面积和农业生态耕种条件保持了改善土壤结构，加权平均直径，微孔率和总孔隙率的条件。在西瓜/南瓜联合会和农业生态耕作中，有机总碳含量的贡献更大，在卡贾拉纳果园地区，西瓜/南瓜联合会的判别变量是粘土，水中的氢离子势能和大孔隙度。因此，多元分析可以分析保水量的变化，这不仅在土地利用之间存在差异，而且在深度和无机土壤组分之间也有所不同。此外，得出的结论是，土壤耕作系统会改变化学物质，
