Effect of vegetation cover and soil moisture on water repellency persistence of drained peat soils

open access: yesBiologia
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]

open access: yes, 2016
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.

微咸水与再生水混灌对土壤特性的影响与灌溉效应评估

open access: yesShuitu Baochi Xuebao, 2022
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]

open access: yes, 2014
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

open access: yesBiologia
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.

The effect of time since last fire occurrence on selected soil hydrological properties in a South African savanna

open access: yesPlant and Soil
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

open access: yesJournal of Hydrology and Hydromechanics, 2017
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 ...

HIDROFOBICIDAD EN ANDISOLES BAJO ROBLEDAL (Quercus humboldtii) Y PLANTACIONES FORESTALES (Pinus patula y Cupressus lusitanica) EN LA CUENCA DE LA QUEBRADA PIEDRAS BLANCAS (MEDELLÍN, COLOMBIA) HYDROPHOBICITY OF ANDISOLS OF OAK GROVES (Quercus humboldtii) AND TREE PLANTATIONS (Pinus patula and Cupressus lusitanica) IN THE PIEDRAS BLANCAS WATERSHED ( MEDELLÍN, COLOMBIA )

open access: yesRevista Facultad Nacional de Agronomía Medellín, 2004
En la cuenca de la quebrada Piedras Blancas se evaluó la persistencia de la repelencia al agua en el horizonte A de Andisoles bajo tres coberturas vegetales: Pinus patula, Cupressus lusitanica y Quercus humboldtii y en tres posiciones topográficas ...

Synchrotron-radiation computed tomography of the water drop penetration time test on hydrophobic soils

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
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
