The breakdown of contaminants in the soil through microbial activity that is enhanced by the presence of the rhizosphere [root zone].

CONT

Rhizodegradation ... is a much slower process than phytodegradation. Microorganisms (yeast, fungi, or bacteria) consume and digest organic substances for nutrition and energy. Certain microorganisms can digest organic substances such as fuels or solvents that are hazardous to humans and break them down into harmless products through biodegradation. Natural substances released by the plant roots -sugars, alcohols, and acids- contain organic carbon that provides food for soil microorganisms, and the additional nutrients enhance their activity.
