Over the last 60 years, soil microbiologists have accumulated a wealth of experimental data
showing that the bulk, macroscopic parameters (eg, granulometry, pH, soil organic matter …

Arbuscular mycorrhizal fungi (AMF) have been presumed to ameliorate crop tolerance to
drought. Here, we review the role of AMF in maintaining water supply to plants from drying …

We report here on recent developments and advances in pore-scale X-ray tomographic
imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid …

Compaction and shearing, as well as the rearrangement of soil aggregates and clods due to
shrinkage, among other processes, can strongly affect the pore geometry of agricultural …

The rhizosphere is the zone of soil influenced by a plant root and is critical for plant health
and nutrient acquisition. All below ground resources must pass through this dynamic zone …

As plant roots take up water and the soil dries, water depletion is expected to occur in the
rhizosphere. However, recent experiments showed that the rhizosphere was wetter than the …

In a handful of fertile soil there are billions of microorganisms and yet, even with a
conservative estimate, the surface area covered by these organisms is considerably less …

Biophysicochemical rhizosheath properties play a vital role in plant drought adaptation.
However, their integration into the framework of plant drought response is hampered by …

Dissolution and precipitation reactions are the primary mechanisms that occur when a rock
(ie, a mineral assemblage) is in contact with a fluid out of equilibrium. They play a critical …

Natural geomaterials often exhibit pore size distributions with two dominant porosity scales.
Examples include fractured rocks where the dominant porosities are those of the fractures …
