Therefore, compared with bulk soils, the activities of free trace metal ions in the soil solution of the rhizosphere in aerobic dryland soils should be even less controlled by precipitation through homogeneous nucleation. In the rhizosphere, precipitation of metals through heterogeneous nucleation on microbial surfaces on the one hand and metal mobilization by biomolecules on the other hand, as a result of root exudation and intense microbial activity, warrants in-depth research for years to come.

1. Global Ion Cycling Transformations and transport of metals and metalloids are part of natural biogeochemical cycling. One of the characteristics of the cycle of metal and metalloid mobilization and deposition is that the form of the metal and metalloid is changed. This change of metal or metalloid speciation has a great effect on its fate and impact on ecosystem health (Benjamin and Honeyman, 1992; Hayes and Traina, 1998; Adriano, 2001). These trace elements are found in the environment in solid, solution, and gaseous phases, associated with thousands of different compounds.
