Relationship between the severity, persistence of soil water repellency and the critical soil water content in water repellent soils

Geoderma, 2014
Abstract Soil water repellency (SWR) causes reduced soil water storage and enhanced runoff and reduced ecosystem productivity. As such, characterization of SWR is a prerequisite for effective environmental management. The objectives of this study were to determine the relationship between the severity of SWR and its persistence and to determine the ...

SOIL-WATER CONTENT DEPENDENCY OF WATER REPELLENCY IN SOILS

Soil Science, 2007
Water repellency (WR) of soils is a global phenomenon. It affects hydrological processes such as infiltration, preferential flow, and surface erosion. Although the soil WR varies nonlinearly with soil-water content (w), WR is often determined at one fixed soil-water content. For a coarse sandy soil, we provide a comparison of the whole WR-w curve under

Soil Water Repellency in Reforested Sandy Soils

2023
Agriculture on sandy soils in Poland was not economical, and in the 1990s, cultivation in these areas was largely abandoned. Consequently, they were mostly overgrown with secondary pine forests, and post-agricultural land in the state forests increased to 22%. The field studies of Albic Podzol overgrown with Pinus sylvestris L.

Modelling soil-water dynamics in the rootzone of structured and water-repellent soils

Computers & Geosciences, 2018
Abstract In modelling the hydrology of Earth's critical zone, there are two major challenges. The first is to understand and model the processes of infiltration, runoff, redistribution and root-water uptake in structured soils that exhibit preferential flows through macropore networks.

USEFUL SOIL-WATER REPELLENCY INDICES

Soil Science, 2008
Water repellency (WR) has been classically characterized at fixed (usually oven-dry) soil water content (θ g ) in terms of the soil water contact angle (CA), a. However, a has been previously reported to depend upon θ g in a nonlinear fashion, such that WR increases from a wettable state close to saturation (θ g-min ) up to a maximum, α max ...

Modeling infiltration into water repellent soil

2023
Infiltration is an important hydrological process impacting ecology, forestry, agronomy, civil- and environmental engineering. Most infiltration models assume soils to be “wettable”, i.e., water in the soil forming an effective contact angle with the soil matrix that is close to zero.

Microplastic enhances water repellency of soils

2020
<p>Soils are the largest sink of microplastic particles (MPP) in terrestrial ecosystems. However, there is little knowledge on the implication of MPP contaminating soils. In particular, we don’t know how MPP move and, on the other hand, how they affect soil hydraulic properties and soil moisture dynamics.</p ...

Manure-Induced Soil-Water Repellency

Soil Science, 2011
AbstractThis laboratory study was conducted to evaluate the potential of nine manure samples from dairy (n = 7), beef (n = 1), and swine (n = 1) to cause water repellency (WR) in six soils; in addition, the duration of WR in two soils was assessed in an incubation study.

Infiltration in water repellent soil

2010
Observations made at Goat Meadows - a small sub-alpine basin located near Pemberton, British Columbia -demonstrated that a layer which is either water repellent or has only a limited affinity for water is present at most vegetated sites. The layer is typically a few centimetres in thickness, and is usually located at or near the top of the profile: it ...
