Effect of vegetation cover and soil moisture on water repellency persistence of drained peat soils
Peatlands play an essential role in the environment and their conservation requires knowledge of water-related processes. Their hydrophobicity is an important factor influencing the flow of water in soils.

The potential of biochar to remove hydrophobic compounds from model sandy soils [PDF]
Charcoals have long been used to adsorb organics from water and other substrates; we hypothesise that biochar may act in a similar way when mixed with soil, removing hydrophobic organic compounds from the soil surfaces.

为了探讨淡水资源不足地区微咸水的合理利用方式。通过盆栽试验, 以清水灌溉为对照, 研究不同比例微咸水与再生水混合灌溉对水盐、水溶性离子、滴水穿透时间WDPT、有机质以及酶活性的影响, 并利用第二代生物综合响应指数法(IBRv2)对微咸水与再生水混灌效应进行评价。结果表明: (1)与再生水灌溉(T1)相比, 随着混合溶液中微咸水比重的升高, 土壤含水率和含盐量逐渐升高且差异显著(P<0.05)。(2)与T1处理相比, 随着混合溶液中微咸水比重的升高, 土壤K+、Ca2+含量呈降低趋势, Na+、Cl ...

Stones resting on the top soil cause heterogeneous patterns of fire-induced water repellency [PDF]
Depending on soil and fire characteristics, soil water repellency (SWR) may be induced, enhanced or destroyed by burning. The spatial pattern of SWR may be extremely heterogeneous as a consequence of the temperature peaks, the variation of fire ...

The relations between soil hydrophobicity and vegetation in abandoned arable fields on sandy soil
The study aimed to find the significant relations between the dominant plant species of secondary succession of lasting abandonment of agricultural fields on sandy soil in central Poland, and soil water repellency strength.

Fires are a natural occurrence in African savannas yet little is known about how fires affect soil hydrological properties over time. This study aimed to determine the short-term (1–9 months post fire) and long-term (> seven decades fire exclusion ...

Impacts of thinning of a Mediterranean oak forest on soil properties influencing water infiltration
In Mediterranean ecosystems, special attention needs to be paid to forest–water relationships due to water scarcity. In this context, Adaptive Forest Management (AFM) has the objective to establish how forest resources have to be managed with regards to ...

The water drop penetration time (WDPT) test consists of placing water drops on a material's surface in order to evaluate how long it takes to penetrate the pores. It is used to evaluate the hydrophobicity of materials. This study aims at investigating in
