Modelling of water droplet dynamics on hydrophobic soils: a review [PDF]

E3S Web of Conferences, 2023
The hydrophobicity of soils (or soil water repellency) can be naturally promoted by wildfires or synthetically induced by hydrophobic compounds (polydimethylsiloxane, tong oil, etc.). Soil phenomena can be related to hydrophobicity, such as soil erosion (

Soil water repellency changes with depth and relationship to physical properties within wettable and repellent soil profiles

Journal of Hydrology and Hydromechanics, 2017
This study explored the effect of soil water repellency (SWR) on soil hydrophysical properties with depth. Soils were sampled from two distinctly wettable and water repellent soil profiles at depth increments from 0-60 cm. The soils were selected because

Molecular Characterization of Burned Organic Matter at Different Soil Depths and Its Relationship with Soil Water Repellency: A Preliminary Result

Agronomy, 2021
Soil water repellency (hydrophobicity) prevents water from wetting or infiltrating soils, triggering changes in the ecosystems. This physical property is directly correlated to the erodibility grade of a soil.

Water repellency in forest soils affected by fires and agricultural soils with different agricultural management and abandonment

Cuadernos de Investigación Geográfica, 2013
Soil water repellency determines the water available in the soil system, the runoff generation and the geomorphologic processes. This study examines the soil wettability during the summer of 2008 and 2009 in forest soils with different fire history, and ...

Impact of secondary succession in abandoned fields on some properties of acidic sandy soils

Journal of Hydrology and Hydromechanics, 2020
Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage.

Application of actinomycetes to soil to ameliorate water repellency [PDF]

Letters in Applied Microbiology, 2002
The aim of this study was to develop a novel isolation technique using a mixture of Bacillus and Streptomyces phages to selectively isolate wax-utilizing non-streptomycete actinomycetes effective in ameliorating water repellency in a problem soil.Phages added to a soil suspension reduced the dominance of Bacillus and Streptomyces isolates and ...

Microbial Effects on Hydraulic Properties of Sewage Sludge-Induced Water-Repellent Soil. [PDF]

Desert
Soil water repellency (SWR) is a widespread natural phenomenon that results from a complex interplay between the hydrosphere, lithosphere, biosphere, atmosphere, and anthroposphere.

Water entrance-and-release capacity and contact angle of improved granite residual soil

Shuiwen dizhi gongcheng dizhi, 2022
Water entrance-and-release capacity of granite residual soil is closely related to the special mechanical properties of softening and disintegration. Existing research on the improved soil focuses on the macro-mechanical properites and variation of micro-

Ground Fire Legacy Effects on Water-Dynamics of Volcanic Tropical Soils

Spanish Journal of Soil Science, 2023
The forest floor is a critical component in maintaining the life cycles of forest ecosystems. It normally includes organic soil horizons, known as duff and litter, which are prone to be rapidly consumed after flaming and smoldering fires.

Rhizosphere-Scale Quantification of Hydraulic and Mechanical Properties of Soil Impacted by Root and Seed Exudates

Vadose Zone Journal, 2018
Using rhizosphere-scale physical measurements, we tested the hypothesis that plant exudates gel together soil particles and, on drying, enhance soil water repellency. Barley ( L. cv. Optic) and maize ( L. cv. Freya) root exudates were compared with chia (
