The pectins are also the main constituents of the mucilaginous soil-root interface (mucigel) they behave as an accumulator for nutrients and are involved in the diffusion process of the ions towards the absorbing cells [7-8]. Electron Microscopy studies provide evidence that these polymers are organised in a fibrillar structure [9-11].

Research on the metal speciation of the soil solution has been encouraged by the free metal ion hypothesis in environmental toxicology (Lund, 1990). This hypothesis states that the toxicity or bioavailability of a metal is related to the activity of the free aquo ion. This hypothesis is gaining popularity in studies of soil-plant relations (Parker et al., 1995). However, some evidence is now emerging that free metal ion hypothesis may not be valid in all situations (Tessier and Turner, 1995). Plant uptake of metals varies with the types of chelators present in solution at the same free metal activity. Furthermore, given the same chelate, total metal concentration in solution affects metal uptake by plants. Either kinetic limitations to dissociation of the complex or uptake of the intact complex could explain these observations (Laurie et al., 1991). The possible reactions of complexed metals at the soil-root interface and the potential uptake by plants of metal-organic complexes are depicted in Figure 1.8.
