Fire-induced changes in soil properties depend on age and type of forests

Journal of Hydrology and Hydromechanics, 2022
Wildfires affect different physical, chemical, and hydraulic soil properties, and the magnitude of their effects varies depending on intrinsic soil properties and wildfire characteristics.

Evaluation of soil properties in variously aged Scots pine plantations established on sandy soil

Journal of Hydrology and Hydromechanics, 2021
Pines are widely planted for sand dune stabilization and their cultivation results in the changes in physical, chemical, hydro-physical and water repellency properties.

The kinetics and energetics of transitions between water repellent and wettable soil conditions: a linear free energy analysis of the relationship between WDPT and MED/CST

Hydrological Processes, 2007
AbstractSoil water repellency is commonly assessed using the Water Droplet Penetration Time (WDPT) and Molarity of Ethanol (MED) or Critical Surface Tension (CST) tests. The former is a kinetic measurement indicating the persistence of water repellency; the latter, a thermodynamic measurement, gives the initial severity of water repellency.

Water stable aggregates of Japanese Andisol as affected by hydrophobicity and drying temperature

Journal of Hydrology and Hydromechanics, 2014
Hydrophobicity is a property of soils that reduces their affinity for water, which may help impeding the pressure build-up within aggregates, and reducing aggregate disruption.

Droplet infiltration dynamics and soil wettability related to soil organic matter of soil aggregate coatings and interiors

Journal of Hydrology and Hydromechanics, 2016
The organo-mineral coatings of soil aggregates, cracks, and biopores control sorption and macropore-matrix exchange during preferential flow, in particular in the clay-illuvial Bt-horizon of Luvisols.

Modification of Soil Hydroscopic and Chemical Properties Caused by Four Recent California, USA Megafires

Fire, 2023
While it is well known that wildfires can greatly contribute to soil water repellency by changing soil chemical composition, the mechanisms of these changes are still poorly understood.

Extent and persistence of soil water repellency induced by pines in different geographic regions

Journal of Hydrology and Hydromechanics, 2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions.

Soil hydrophobicity: comparative study of usual determination methods

Ciência Rural, 2015
Hydrophobic or water repellent soils slowly absorb water because of the low wett ability of the soil particles which are coated with hydrophobic organic substances. These pose significant effects on plant growth, water infiltration and retention, surface

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.

Impact of duration of land abandonment on soil properties

Journal of Hydrology and Hydromechanics, 2023
Abandonment of agricultural fields triggers the ecosystem recovery in the process referred to as secondary succession. The objective of this study was to find the impact of secondary succession during 12 years lasting abandonment of agricultural fields ...
