Figure 9: Examples of Mollisols (grassland soils) formed from loess. Both soils have mean annual precipitation of 450 mm. The Ustoll (a) has an ustic soil moisture regime and the Xeroll (b) has a ...

Soils lose moisture quickly during droughts because the molecular interactions that help retain water are not fully understood. Understanding this mechanism can help engineer soils to better preserve ...

From the lava plains of the Alvord Desert to the fertile alluvium of the Willamette Valley, Oregon’s secret wealth is lying all around us. It’s an ingredient forged from stars, fire and ice and, ...

From mixed charges to chemical bonding, Professor Ludmilla Aristilde found that iron uses multiple strategies to lock carbon away.

Soil microbes remove carbon from the atmosphere and store it underground, revealing an overlooked pathway for storage in ...

A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced. In certain trees, soils can form along branches and can support ...

DURHAM, N.C. – A new book coauthored by Duke University's Daniel Richter documents the extraordinary history of soils of the southeastern United States, where fields of a former vast cotton belt are ...

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal ...

In certain trees, soils can form along branches and can support varied plant and animal life. However, what conditions these ‘canopy soils’ form in, and what kind of biodiversity they support, has ...
