Abstract

To quantify water and ion uptake by older suberized roots, a root chamber for field experiments was developed. The plexiglass chamber can be installed at intact coarse roots of mature trees including root diameters up to 5 cm. After filling the chamber with a nutrient solution, changes in water volume and ion concentration are recorded for several weeks throughout the growing season — to investigate the influence of different stages of growth and different weather conditions. The root chamber method proved to be able for measuring water and ion uptake through coarse tree roots in the field, where access to the root system is normally difficult.
