The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

Gypsum and structure lime amendments in boreal agricultural clay soils: Do climate emissions compromise water quality benefits?

Agricultural and Food Science
We examine cost-effectiveness and social net benefits of using soil amendments, gypsum and structure lime, in reducing phosphorus loading while accounting for the climate emissions from both amendments. Recent field experiments and large-scale pilots in

Abrupt Onset and Persistent Downstream Effects of Acid Rock Drainage on Rivers Across Northwest Arctic Alaska

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Arctic streams and rivers are increasingly vulnerable to degradation from permafrost thaw that releases toxic elements via natural acid rock drainage. However, the spatial and temporal evolution of acid rock drainage on river chemistry across diverse mineral settings remain poorly constrained.

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Effects of polyacrylamide and gypsum on soil erosion and sediment transport

, 2008
This study evaluates the effectiveness of two popular soil amendments of gypsum and polyacrylamide (PAM), in minimizing soil erosion from one soil and one overburden (spoil) material of a mine rehabilitation site in North Queensland.

Can soil amendments help stabilize rainfed soybean production variations?

Agrosystems, Geosciences & Environment
The application of biochar and gypsum to soil promotes soil health for crop production. The benefits can vary depending on the soil and climate. We evaluated seed yield, quality, and soil quality benefits of applying biochar and gypsum to silt loam soil ...

Plants Uptake Substantial Water From the Surface Organic Layer in Highly Permeable Karst Critical Zones

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Plants growing in highly permeable karst critical zones are exposed to shallow soils and rapid hydrological turnover. The surface organic layer is recognized as a key ecohydrological interface in these environments, yet its direct contribution to plant water uptake has rarely been quantified.

Insights Into Soil Health in Sugarcane From a Bibliometric Analysis: Brazil's Scientific Contribution to the World

GCB Bioenergy, Volume 18, Issue 9, September 2026.
This bibliometric review (2000–2025) reveals a sharp increase in publications and citations on sugarcane soil health after 2010, driven by mechanized harvesting and climate–bioenergy policies. Research is spatially concentrated in São Paulo State and dominated by chemical and physical indicators, with biological attributes remaining underrepresented ...
