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,

Critical conditions for the wetting of soils [PDF]

, 2006
The wettability of soil is of great importance for plants and soil biota and in determining whether flooding and soil erosion will occur. The analysis used in common measurements of soil hydrophobicity makes the assumption that water always enters soils ...

Synchrotron-radiation computed tomography of the water drop penetration time test on hydrophobic soils

Journal of Rock Mechanics and Geotechnical Engineering
The water drop penetration time (WDPT) test consists of placing water drops on a material's surface in order to evaluate how long it takes to penetrate the pores. It is used to evaluate the hydrophobicity of materials. This study aims at investigating in

Water-repellent soil and its relationship to granularity, surface roughness and hydrophobicity: a materials science view [PDF]

, 2005
Considerable soil water repellency has been observed at a wide range of locations worldwide. The soil exhibiting water repellency is found within the upper part of the soil profile.

Assessment of the Effects of the 2021 Caldor Megafire on Soil Physical Properties, Eastern Sierra Nevada, USA

Fire, 2023
The Caldor fire burned ~222,000 acres of the Eastern Sierra Nevada during summer–fall 2021. We evaluated the effects of this “megafire” on the physical properties of a sandy soil developed from glacial tills to document fire-induced soil modifications in

Alterations in aggregate characteristics of thermally heated water-repellent soil aggregates under laboratory conditions

Journal of Hydrology and Hydromechanics, 2023
The heat generated during wildfires modifies soil characteristics, including soil water repellency (SWR) and the water stability of aggregates, which are known to be interrelated.

Wheat Yield Response to Organic Fertilisers Depends on Drought Timing in a Sandy Soil

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Organic fertilisers enhance crop drought resilience by improving nitrogen (N) and phosphorus (P) use efficiency and soil‐plant water relations. However, the underlying mechanisms governing their effects across different drought timings in wheat under sandy soils remain unclear.

The southwest Kalahari dune field does not emit dust post‐fire despite a lack of vegetation and above‐threshold winds

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
The southwest Kalahari dune field has resident fine grains which may be emitted as mineral dust after protective vegetation is removed by fire. However, low wind speeds, high initial surface cover, and the protective effect of biocrusts result in the low possibility of the southwest Kalahari emitting dust post‐fire.

Impact of climate, soil properties and grassland cover on soil water repellency [PDF]

, 2021
Numerous soil water repellency (SWR) studies have investigated the possible causes of this temporal phenomenon, yet there remains a lack of knowledge on the order of importance of the main driving forces of SWR in the context of changing environmental ...
