2016-3-13 · Rhizosphere Root Interactions Source. The rhizosphere is a microecological zone in direct proximity of plant roots. It is often operationally defined as the soil that clings to roots after being gently shaken in water. The actual extent of the rhizosphere is dependent on the zone of influence of the plant roots and associated microorganisms.
