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 …

Background The need to observe roots in their natural undisturbed state within soil, both
spatially and temporally, is a challenge that continues to occupy researchers studying the …

Abstract Structure represents one of the main soil physical attributes indicators. The soil
porous system (SPS) is directly linked to the soil structure. Water retention, movement, root …

Soil systems are characterized by the spatial and temporal distribution of organic and
mineral particles, water and air within a soil profile. Investigations into the complex …

Computed tomography (CT) in combination with advanced image processing can be used to
non-invasively and non-destructively visualize complex interiors of living and non-living …

Roots naturally exert axial and radial pressures during growth, which alter the structural
arrangement of soil at the root–soil interface. However, empirical models suggest soil …

Despite the critical importance of roots within soils for supporting plant growth, the
assessment of root distribution in soils remains difficult and much is unknown regarding their …

The representative elementary volume (REV) is related to the minimum size of a sample that
is necessary for representative measurements of a property. The REV is frequently …

Measurements of soil bulk density can aid our understanding of soil functions and the effects
of land use and climate change on soil organic carbon (C) stocks. Current methods for …

Maintaining or increasing soil organic carbon (C) is vital for securing food production and for
mitigating greenhouse gas (GHG) emissions, climate change, and land degradation. Some …
