Soil physical quality loss is mainly caused by compaction and soil structure deterioration. Both these processes influence water dynamic attributes such as hydraulic conductivity at saturation and sorptivity, as shown in field and laboratory studies with soil aggregates or soil samples preserved inside jackets. This study aimed: (i) to assess the link between different vegetation covers and physical attributes used to describe soil water dynamics and potential soil water repellency; and (ii) to identify whether these attributes recovered after 17-year revegetation with leguminous trees. The experimental area is located in Conceição de Macabú County, Rio de Janeiro State, Brazil. Soil aggregates were applied to tests with a miniaturized tension infiltrometer, allowing to obtain several soil hydrodynamic variables. For the surface horizon, soil hydrophobic behavior did not occur under pasture but occurred under tree covers, with the natural forest and sabiá sites being the highlights. For the subsurface horizon, the natural forest and sabiá sites were classified as non-hydrophobic and the pasture site as hydrophobic, as opposed to what was verified for the surface horizon. For both horizons, the soil under leguminous trees presented results close to those of the soil under forest, and very different from those of soil under pasture. Potential hydrophobicity levels justify the obtained opposite-to-expected hydrodynamic results, such as the lower conductivity and sorptivity occurring despite the lowest compaction and the higher conductivity and sorptivity occurring despite the highest compaction. Therefore, it was concluded that potential hydrophobicity levels affect hydrodynamic attributes and that revegetation using leguminous tree species leads to recovery of the natural soil conditions and perhaps their capacity to exert their original ecological functions.

土壤物理质量损失主要由板结和土壤结构恶化引起。这两个过程都会影响水的动态属性，例如饱和时的水力传导率和吸附性，如现场和实验室研究所示，土壤团聚体或土壤样品保存在夹套内。本研究旨在：(i) 评估不同植被覆盖与用于描述土壤水分动态和潜在土壤疏水性的物理属性之间的联系；(ii) 确定这些属性在豆科树木重新植被 17 年后是否恢复。实验区位于巴西里约热内卢州康塞桑德马卡布县。使用微型张力渗透计将土壤团聚体应用于测试，从而获得几个土壤水动力变量。对于地平线，sabiá网站是亮点。对于地下地平线，天然森林和sabiá地点被归类为非疏水性的，牧场地点被归类为疏水性的，这与地表地平线所验证的情况相反。对于这两个层位，豆科树下土壤的结果与森林下土壤的结果接近，而与牧场下的土壤非常不同。潜在的疏水性水平证明了所获得的与预期相反的流体动力学结果是合理的，例如尽管压实度最低，但导电率和吸附性较低，而尽管压实度最高，但导电率和吸附性较高。因此，可以得出结论，潜在的疏水性水平会影响水动力属性，并且使用豆科树种进行重新植被会导致自然土壤条件的恢复以及它们发挥原始生态功能的能力。
