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 ...

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 ...

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 ...
