Aggregation agents and structural stability in soils with different texture and organic carbon contents

open access: yesScientia Agricola, 2015
The flat pampas in the state of Santa Fe in Argentina have soils with high silt content, variable carbon content, and diverse degrees of structural degradation.

Aggregation characteristics and maturity of Peak District soils [PDF]

open access: yes, 1969
Soil aggregation and aggregate stability are fundamental factors in determination of soil erodibility. The aggregation characteristics of soils in a region of high erosion potential are measured, and controlling factors examined.

Migration of Per‐ and Polyfluoroalkyl Substances in Soil Under Rainfall Simulation

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
A rainfall simulation is conducted to evaluate the migration of PFAS in soil spiked with aqueous‐film‐forming foam during rainfall. Most PFAS migrate via leaching, followed by runoff. High PFAS concentration in soil (⩾30 mg/kg) could alter soil hydraulic conductivity and inhibits leaching.

Effect of environmental pollution on susceptibility of sesquioxide-rich soils to water erosion

open access: yesGeology, Ecology, and Landscapes, 2018
This work assessed the impact of environmental pollution on soils susceptibility to water erosion within South-eastern Nigeria. Sources of pollutants which could possibly affect the chemical composition of runoff; hence its pH, were first determined by ...

Increasing Population and Cropland Exposure to Human‐Induced Sequential Heatwave‐Downpour Events

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Compound sequential heatwave‐downpour (SHD) events, characterized by abrupt shifts from heatwaves to heavy rainfall, pose serious threats to health, infrastructure, and agriculture. However, the anthropogenic influence on the increasing trend of SHD events is poorly understood, and projections also exhibit large uncertainties.

Comportamiento hídrico de pizarras de techar

open access: yesMateriales de Construccion, 1990
The hidric behaviour of two slaty rocks from the NW of Spain (phyllite of Rande —La Coruña— and slate of Luarca —Asturias—) used as ornamental and roof slate is studied.

Biodiversity and soil type modulate the effect of plastic contamination on soil functioning

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings show that the negative effects of plastic contamination on soil functioning strongly depend on soil type and can be partly alleviated by plant diversity. In sandy soils, diverse plant communities buffered functional losses under plastic stress, whereas in clayey soils the benefits of diversity were suppressed.

Is solid calcium looping a scalable technology for mega-ton carbon dioxide removal?

open access: yesJournal of CO2 Utilization
Atmospheric CO2 removal at Gton scale is necessary to limit global temperature rise. This study provides essential insights into the energy, area, and water requirements of solid calcium looping for large-scale CO2 removal, combining experimental results

Weathering Influence on Properties of Siltstones from Istria, Croatia

open access: yesAdvances in Materials Science and Engineering, 2016
Slaking and weathering of weak rocks result in slope instability. Siltstones from flysch rock masses are highly susceptible to weathering, which causes rapid changes in the geotechnical properties and durability. This study investigated siltstone samples

Cover crop residues effect on soil structural stability and phosphatase activity

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2021
Good soil aggregate stability and soil enzyme activity are strictly necessary for the proliferation of plants growth and soil resistance against erosion. In this study, the goal was to investigate the effect of different cover crops on the soil aggregate
