Open AccessA comparison between water uptake and root length density in winter wheat: effects of root density and rhizosphere properties
We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots.

Open AccessBrachiaria species influence nitrate transport in soil by modifying soil structure with their root system
Leaching of nitrate from fertilisers diminishes nitrogen use efficiency (the portion of nitrogen used by a plant) and is a major source of agricultural pollution. To improve nitrogen capture, grasses such as b...

Open AccessPhacelia (Phacelia tanacetifolia Benth.) affects soil structure differently depending on soil texture
We studied the effects of Phacelia tanacetifolia, increasingly used as a cover-crop species in arable agricultural systems, upon soil structural properties in the context of two contrasting soil textures. We hypo...

Open AccessThe emergent rhizosphere: imaging the development of the porous architecture at the root-soil interface
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 prior to their capture b...

Develo** X-ray Computed Tomography to non-invasively image 3-D root systems architecture in soil
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 rhizosphere.

The micromorphology of selected Irish milled peats
The movement of water in milled peat is of importance to the peat industry particularly in terms of rewetting. Considering the importance of structure with regard to water flow, micromorphology was used to obt...

Morphological observations of dye tracer infiltration and by-pass flow in milled peat
Dye tracers provide a direct means in which to visualise flow paths and interpret active wetting mechanisms in soil. Until recently it had been assumed that rewetting in milled peat took place by surface wetti...
