Water repellency of sandy soil as a function of hydrophobic concentration Influência da concentração de extratos hidrofóbicos na repelência à água em solos arenosos

Pesquisa Florestal Brasileira, 2011
<p>Soil water repellency has been reported worldwide being most extremes cases observed in sandy soils. Soil  water repellency is accepted to be caused by recovering  of soil particles by hydrophobic compounds originated  from plant decomposition ...

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,

Low‐intensity prescribed fire has no immediate impact on soil physical and chemical properties or enzymatic activity in the Post Oak Savanna ecoregion, Texas, USA

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract The historic development of the Post Oak Savanna ecoregion in Texas, USA, was shaped by natural wildfires. However, wildfire suppression has caused an increase in encroaching woody species. To address this issue, land management strategies incorporate prescribed fire (PF) for the control of encroaching species.

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.

Evaluating the Economic Impacts of Climate Change on Aotearoa–New Zealand's Dairy Sector

Australian Journal of Agricultural and Resource Economics, Volume 70, Issue 1, Page 71-86, January 2026.
ABSTRACT This study examines the economic impacts of climate change on Aotearoa‐New Zealand's (A‐NZ) dairy sector, a critical contributor to the nation's GDP and global agricultural trade. Using a combination of biophysical and economic modelling, including the Dairy Sector Pathways (DSP) model and a multi‐country partial equilibrium model (LTEM), the ...

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

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
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 lot of influencing factors.
