Rethinking Global Soil Degradation: Drivers, Impacts, and Solutions

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could ...

Chemical weathering of the volcanic soils of Isla Santa Cruz (Galápagos Islands, Ecuador) [PDF]

, 2014
We present a study on weathering of volcanic soils using 43 profiles (131 horizons) sampled in Santa Cruz Island (Galapagos Islands). Several weathering indices, based on chemical composition, are used. Since the geological material is highly homogeneous

Phosphate system fertilization in no‐tillage Oxisols: Effects of temporal, horizontal, and vertical distribution of available phosphorus in the soil

Journal of Environmental Quality, Volume 54, Issue 6, Page 1352-1367, November/December 2025.
Abstract System fertilization enhances logistics and phosphorus (P) use efficiency, but its effects in high P‐export systems, particularly regarding fertilization timing, placement, and distribution, remain unclear. This study evaluated P fertilization timing (90, 45, and 0 days before winter crop sowing [DBS]), placement (banded vs.

Clay‐Mineral‐Coated Separators for Lithium‐Ion Batteries: Exploring the Relationships between Clay Mineral Morphology and Separator Performance

Advanced Science, Volume 12, Issue 40, October 27, 2025.
This review examines how coating Li‐ion battery separators with 1D, 2D, and 3D structured natural clay minerals influences their electrochemical and mechanical performance. It classifies 15 types of clay minerals and highlights structure–property correlations to offer practical design strategies for high‐performance separators in next‐generation energy

Frustration of the isotropic-columnar phase transition of colloidal hard platelets by a transient cubatic phase

, 2011
Using simulations and theory, we show that the cubatic phase is metastable for three model hard platelets. The locally favored structures of perpendicular particle stacks in the fluid prevent the formation of the columnar phase through geometric ...

Potential pitfalls when using popular chemical extractions to characterize Al‐ and Fe‐containing soil constituents

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 730-741, October 2025.
Abstract Wet‐chemical extraction of soil to quantify pedogenic species or to remove specific compounds prior to other analyses is an established approach in analytical soil mineralogy and soil chemistry. Interpretation and informational value of data derived from long‐established and frequently used extractions, for instance involving dithionite ...
