rhizosphere - Zone of soil immediately surrounding roots which is modified by their activity. It is characterized by enhanced micro-biological activity and often by changes in relative proportions of types of organisms present compared with surrounding soil; due to changes in nutrient status of soil arising from removal of nutrients by root absorption and release of others in root exudation and by sloughing off of dead cells. Within the rhizosphere a further micro-environment is often distinguished, namely, the rhizoplane or root surface.
