Comparison of Water-Repellent Detection Agents and Evaluation System Optimization of Soil Water-Repelling Rate

Advances in Civil Engineering
The determination and evaluation of severity rating of soil is an important part of the research on the engineering properties of water-repellent soil. It is still difficult to accurately obtain the soil water-repelling rate in essence, and there are a ...

The Film-Forming Characterization and Structural Analysis of Pectin from Sunflower Heads

International Journal of Polymer Science, 2021
A natural low-methoxyl pectin (termed AHP, DM=25.9%) was extracted from dried heads of sunflower and showed better film-forming performance blended with hydroxypropyl methylcellulose (HPMC).

Water repellency in eucalyptus and pine plantation forest soils and its relation to groundwater levels estimated with multi-temporal modeling

Journal of Hydrology and Hydromechanics, 2020
Water repellency makes soils capable of resisting to the penetration of water applied on the surface and inflict various influences on groundwater.

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.

Heat-induced alterations in moisture-dependent repellency of water-repellent forest soils: A laboratory approach with Japanese Andosols

Journal of Hydrology and Hydromechanics
Soil water repellency (SWR) is a phenomenon that prevents the spontaneous wetting of numerous forest soils. It is a moisture-dependent characteristic, which disappears when soil moisture reaches near saturation.

Biological soil crusts cause subcritical water repellency in a sand dune ecosystem located along a rainfall gradient in the NW Negev desert, Israel

Journal of Hydrology and Hydromechanics, 2016
The biological soil crusts (BSCs) in the NW Negev cause local water redistribution by increasing surface runoff. The effects of pore clogging and swelling of organic and inorganic crust components were intensively investigated in earlier studies. However,

Use of Clay Dispersed in Water for Decreasing Soil Water Repellency [PDF]

, 2017
In this study, we examined the efficiency of a kaolinite clayey soil to mitigate water repellency of a sandy soil with olive trees. The treatment was applied to the soil zone below the tree canopy, which displayed the highest degree of water repellency ...

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

Plant, 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.
