Abstract

Transport phenomena in the root zone contribute to transfers which take place in the whole soil-plant-atmosphere system. They are often determinant for the circulation of elements towards and in the atmosphere and also towards surface and underground waters. Several sink and source phenomena control the liquid phase composition in the root zone, and then, play an important role in solute transfer processes. This role is illustrated by some examples.
