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

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.

Superhydrophobic surfaces: a model approach to predict contact angle and surface energy of soil particles [PDF]

, 2009
Wettability of soil affects a wide variety of processes including infiltration, preferential flow and surface runoff. The problem of determining contact angles and surface energy of powders, such as soil particles, remains unsolved.

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-

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 (

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.

Initial water repellency affected organic matter depletion rates of manure amended soils in Sri Lanka

Journal of Hydrology and Hydromechanics, 2014
The wetting rate of soil is a measure of water repellency, which is a property of soils that prevents water from wetting or penetrating into dry soil.
