Rhizosphere is the zone around the plant root, including the root, the soil on the root and the surrounding soil that is influenced by the roots. Microorganisms that live in that complex habitat affect the health of plants and their yield. Knowledge of the composition and quantity of organic compounds that are released by roots provides insight into the chemical and biological processes that occur in the rhizosphere. Each plant species selects its own specific bacterial community from a reservoir of bacteria present in the soil or on the seed. Using natural resources in a sustainable microbial agricultural production is based on the multiplication of active species and strains of microorganisms in artificial conditions and returning in their natural environment – soil where these microorganisms intensify the appropriate processes, produce more plant nutrients, stimulate the growth of plants and protect them from pathogens and toxic substances. These microorganisms may partially or completely replace mineral fertilizers and pesticides.
