Measuring and Imaging the Soil-root-water System with a Light Transmission 2D Technique
Bio-Protocol, 2019 Improving crops against water deficits requires a better understanding of plant root system functioning. This requires a better knowledge of the water uptake process and to address the influence of root system architecture or root physiological ...

Theoretical analysis of coupled effects of microbe and root architecture on methane oxidation in vegetated landfill covers [PDF]
, 2017 Reduction of soil moisture by plant root-water uptake could improve soil aeration for microbial aerobic methane oxidation (MAMO) in a landfill cover, but excessive soil moisture removal could suppress microbial activity due to water shortage.

Quantification of root water uptake in soil using X-ray Computed Tomography and image based modelling [PDF]
, 2017 Spatially averaged models of root-soil interactions are often used to calculate plant water uptake. Using a combination of X-ray Computed Tomography (CT) and image based modelling we tested the accuracy of this spatial averaging by directly calculating ...

Implementing small scale processes at the soil-plant interface – the role of root architectures for calculating root water uptake profiles [PDF]
Hydrology and Earth System Sciences, 2010 In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root network. The boundary conditions for the model are the

Architectural Root Responses of Rice to Reduced Water Availability Can Overcome Phosphorus Stress
Agronomy, 2018 Drought and low phosphorus (P) availability are major limitations for rainfed rice production. Crop roots are important for soil resource acquisition and tolerance to P and water limitations.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]
, 2009 In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...
