TL;DR: The root water uptake from local and regional to global scales was discussed at a workshop in Gif-sur-Yvette, France, with the central objective to develop a research strategy for the next 3-5 years, aiming at a systematic description of root functioning, rooting depth, and root distribution as discussed by the authors.

Abstract: From 30 September to 2 October 1999 a workshop was held in Gif–sur–Yvette, France, with the central objective to develop a research strategy for the next 3–5 years, aiming at a systematic description of root functioning, rooting depth, and root distribution for modeling root water uptake from local and regional to global scales. The goal was to link more closely the weather prediction and climate and hydrological models with ecological and plant physiological information in order to improve the understanding of the impact that root functioning has on the hydrological cycle at various scales. The major outcome of the workshop was a number of recommendations, detailed at the end of this paper, on root water uptake parameterization and modeling and on collection of root and soil hydraulic data.

Modeling Root Water Uptake, Climate and Unsaturated Vegetated Clays Interactions in the Context of Shallow Foundation Soils
Hossein Assadollahi,Hossein Nowamooz +1 more
- 24 Nov 2018
TL;DR: In this paper, a root water uptake model was used along with the atmospheric boundary condition to model the tree root effect on the soil suction, water content and temperature, and the results showed that the water uptake by tree roots does not influence the soil right under the foundation of the building.

A Big Root Approximation of Site-Scale Vegetation Water Uptake
TL;DR: In this article, the authors derive a big root approach from the porous pipe equation for root water uptake and compare its predictions of soil moistures during the 2010 summer drought at the Wind River Crane site to two previously used Ohm's law analogue plant hydraulic models.

TL;DR: In this article, the authors analyzed mixtures of sand for golf putting green construction and added up to 10 mass percent by measuring their water retention in soil cores and modeling soil water storage and drainage under a reaslistic water application schedule.

TL;DR: In this article, a coupled hydrogeophysical approach with both time domain reflectometry soil water content and electrical resistivity measurements was used to compare root water uptake and soil properties of an annual crop rotation with the perennial grass miscanthus, across three growing seasons (2009-2011) in southwest Michigan, USA.

A closed-form equation for predicting the hydraulic conductivity of unsaturated soils
van Genuchten,M. Th. +1 more
TL;DR: Van Genuchten et al. as mentioned in this paper proposed a closed-form analytical expression for predicting the hydraulic conductivity of unsaturated soils based on the Mualem theory, which can be used to predict the unsaturated hydraulic flow and mass transport in unsaturated zone.

Crop salt tolerance–current assessment
Eugene V. Maas,G. J. Hoffman +1 more
TL;DR: An extensive literature review of all available salt tolerance data was undertaken to evaluate the current status of our knowledge of the salt tolerance of agricultural crops as mentioned in this paper, concluding that crops tolerate salinity up to a threshold level above which yields decrease approximately linearly as salt concentrations increase.

TL;DR: Rooting patterns for terrestrial biomes are analyzed and distributions for various plant functional groups are compared and the merits and possible shortcomings of the analysis are discussed in the context of root biomass and root functioning.

Maximum rooting depth of vegetation types at the global scale.
Josep G. Canadell,Robert B. Jackson,James R. Ehleringer,Harold A. Mooney,Osvaldo E. Sala,Ernst Detlef Schulze +5 more
TL;DR: Deep root habits are quite common in woody and herbaceous species across most of the terrestrial biomes, far deeper than the traditional view has held up to now, and has important implications for a better understanding of ecosystem function and its application in developing ecosystem models.
