Water-entry pressure in water repellent soils: a review [PDF]

open access: yesE3S Web of Conferences, 2020
Water repellent soils can be naturally promoted (e.g. after wildfires) or synthetically induced by mixing with hydrophobic compounds (e.g. polydimethylsiloxane).

A brief overview of the causes, impacts and amelioration of soil water repellency - a review

open access: yesSoil and Water Research, 2008
This article describes the phenomenon of soil water repellency, starting from the fundamental principals of water transport and storage in soil. Soil water repellency is a reduction in the rate of wetting and retention of water in soil caused by the ...

Water repellency decreases with increasing carbonate content and pH for different biocrust types on sand dunes

open access: yesJournal of Hydrology and Hydromechanics, 2021
Biocrusts are biological communities that occupy the soil surface, accumulate organic matter and mineral particles and hence strongly affect the properties of the soils they cover.

Identifying the origin of soil water repellency at regional level using multiple soil characteristics: The White Carpathians and Myjavska pahorkatina Upland case study

open access: yesSoil and Water Research, 2015
This paper evaluates the relationship between water repellency and multiple characteristics of topsoil samples belonging to seven Reference Soil Groups, taken from the area of the White Carpathians and the Myjavska pahorkatina Upland.

Variability of water repellency in sandy forest soils under broadleaves and conifers in north-western Jutland/Denmark

open access: yesSoil and Water Research, 2008
Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been known to occur on a wide range of sites under a variety

Effects of kaolinite and drying temperature on the persistence of soil water repellency induced by humic acids

open access: yesPlant, Soil and Environment, 2002
The effects of kaolinite additions and drying temperature on the persistence of soil water repellency, induced by humic acids from peat, were assessed in this study.

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

open access: yesCuadernos 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 ...

Synthesis of Nontoxic and Bio Based Oil and Water Repellent Polymers for Cotton Fabrics Using Stearic Acid, Succinic Acid, and Itaconic Acid

open access: yesJournal of Natural Fibers, 2022
Fluorocarbon-based oil and water repellents are considered best in textile finishing due to their excellent performance. Although, long chain fluorocarbons are effective oil and water repellents but they are toxic and being banned. Therefore, the present

Effect of kaolinite and Ca-montmorillonite on the alleviation of soil water repellency

open access: yesPlant, Soil and Environment, 2004
The effects of adding 1-3% (weight) kaolinite or Ca-montmorillonite on the wettability of silica sand, made highly water repellent with stearic acid, was studied during wetting and prolonged drying phases at 50°C.
