Titre : Soil pores hold the key to stability for desert soils

Soils in deserts are very different from those found anywhere else. Extreme temperatures, little water and limited plant matter make an unusual environment. With little dead plant material to decompose and create a rich layer of organic matter, desert soils are unique.

Présentation
Vesicular pores are spherical, look a bit like bubbles, and are not connected to each other. Vughs are similar but more irregular in shape, almost like a clump of bubbles that have not fully separated from each other.

Turk wanted to learn how these horizons form across different desert soils. In their most recent experiment, they chose small plots of the soils and took samples. They then crushed the soil so the formation of pores would have to start from scratch. They checked the porosity of the soils over the course of a year to compare.
