Biogeochemical processes rhizospheric

The rhizosphere, which is characterized by distinct physical, chemical, and biological conditions (Figures 1.14 and 1.15), is the focal point of the potential role of higher plants in accelerating natural remediation in contaminated soils. Rhizosphere conditions are created by the plant roots and their microbial associations. Rhizospheric biogeochemical processes are influenced substantially by soil physical, mineralogical, chemical, and biological features and also by edaphic and climatic conditions. Special tools and techniques are required to study the characteristics and processes of the rhizosphere because of its limited areal extension (Wenzel et al., 2001).
