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

Effects of Acacia dealbata Invasion and Removal on Soil and Vegetation in Communal Grasslands in Eastern Cape, South Africa

African Journal of Ecology, Volume 63, Issue 7, October 2025.
ABSTRACT Acacia dealbata has invaded South African grasslands, yet few studies have assessed its invasion and clearing effects on grasslands. We assessed the soil (moisture, repellency, penetration resistance, infiltration rate and hydraulic conductivity) and vegetation (diversity, composition and cover) impacts of A.

The influence of irrigation with Lake Kinneret water on the chemistry of soils in the headwater basin

Soil Science Society of America Journal, Volume 89, Issue 3, May/June 2025.
Abstract The farming areas in the catchment of Lake Kinneret basin are irrigated with Dan Spring waters, characterized by a concentration of 10 mg/L of Cl. Climate change simulation predicts that by the year 2050, the flow of the headwater springs will drop by 20%, a finding that poses a significant threat to the future of farming in the basin.

Minimal Soil Impacts of Caesalpinia decapetala Invasion in South Africa's Vhembe Biosphere Reserve

African Journal of Ecology, Volume 63, Issue 2, March 2025.
ABSTRACT We assessed the effects of Caesalpinia decapetala (Roth) Alston invasion on soil physical properties over 3 summer months in Vhembe Biosphere Reserve, South Africa. Topsoils were collected beneath replicated invaded and uninvaded conditions and assessed for soil moisture, water repellency, penetration resistance, infiltration and hydraulic ...

Finer Measurement Scales for Induced Hydrophobicity Using the Water Droplet Penetration Test

Geotechnics
The Water Droplet Penetration Test (WDPT) is commonly used in most soil water repellency (SWR) research and is particularly prominent in field studies after wildfire events.

Biochar impacts on soil moisture retention and respiration in a coarse‐textured soil under dry conditions

Soil Science Society of America Journal, Volume 88, Issue 6, Page 1919-1931, November/December 2024.
Abstract The growing water scarcity jeopardizes crop production for global food security, a problem poised to worsen under climate change–induced drought. Amending soils with locally derived biochar from pyrolyzed agricultural residues may enhance soil moisture retention and resilience, in addition to climate change mitigation.

Quantitative experimental study on the apparent contact angle of unsaturated loess and its application in soil–water characteristics curve modeling

Vadose Zone Journal, Volume 23, Issue 6, November/December 2024.
Abstract Advancing and receding water contact angles, often denoted as the maximum and minimum apparent water contact angles, are crucial parameters reflecting a soil's water holding capacity. These parameters play an important role in establishing theoretical soil–water characteristic curves (SWCCs) for unsaturated soils.

Continuous Monitoring of Vegetation and Soil Recovery After Eucalyptus grandis Removal in Dense Trees and Shrubs Areas

African Journal of Ecology, Volume 62, Issue 3, September 2024.
ABSTRACT Invasion by invasive alien plants is a global challenge and South Africa has invested billions of Rands to manage invaders through the Working for Water programme. However, regular monitoring after alien plant clearing is hardly done, yet it forms the basis for assessing clearing programme effectiveness, particularly ecosystem recovery ...

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).

Dynamic contact angle as a new metric for the water repellency evaluation of biochar-amended soil

Biochar
Biochar hydrophobicity is crucial for understanding its interaction with environmental substances (e.g., soil, water, pollutants). Contact angle (CA) and water droplet penetration time (WDPT) are commonly used methods for assessing biochar hydrophobicity.
