Definition

Root water uptake (water extraction or water absorption): water flow from the soil to the root.

3D functional approaches (or functional–structural plant modeling): modeling approach aiming at representing virtual plants with their three-dimensional (3D) architecture and selected physiological functions.

Introduction

Water is an essential resource for plant life. Typically, cropped plants transpire 200–1,000 kg of water for each kilogram of dry matter produced (Martin et al., 1976), and this water is principally extracted from the soil by the roots. Therefore, modeling of soil water uptake by plant roots is of importance for a series of environmental and agronomic purposes. Numerous practical applications like yield prediction, irrigation management, or pollutant fate prediction under cropped fields need a detailed understanding of the interactions between soil water and roots to be investigated as well as advanced modeling approaches.

The uptake of water by roots is mainly a...
