The rhizosphere is the zone of soil that surrounds the roots of plants and is characterized by the presence of a variety of organic exudates released by the roots.

Mycorrhizae are symbiotic associations between fungi and plant roots, and while they may also be present in the rhizosphere, they do not define the zone itself. Rootsphere is not a recognized term in soil science. Geosmin is an organic compound that can give soil and water an earthy or musty odor, but it does not describe a specific zone in the soil.
