What is the rhizosphere?
(The rhizosphere is a biological bazaar (market place) where microbes and plants trade nutrients, metabolites, and exudates)
Rhizosphere refers to the area of soil that is directly affected by a plant’s root system, associated root secretions, and microorganisms.
The rhizosphere region around a plant’s roots contains an abundance of bacteria and microorganisms that depend on the plant’s sloughed off cells, sugars, and proteins as a primary food source. In exchange, the bacteria and microorganisms help create a nutrient-rich, aerated place for the plant’s roots.
Within the rhizosphere, the coexistence of bacteria, plants, and micro-organisms create a key symbiotic relationship. The rhizosphere is where a plant's mycorrhizal fungi are present.
