Plant Beneficial Microbes

Plant growth-promoting bacteria (PGPB) occupy the rhizosphere of many plant species and have beneficial effects on the host plant. They may influence the plant in a direct or indirect manner. A direct mechanism would be to increase plant growth by supplying the plant with nutrients and hormones; Indirect mechanisms on the otherhand, include, reduced susceptibility to diseases, and activating a form of defense referred to as induced systematic resistance. Soil microorganisms are the most abundant of all the biota in soil and responsible for driving nutrient and organic matter cycling, soil fertility, soil restoration, plant health and ecosystem primary production. Beneficial microorganisms include those that create symbiotic associations with plant roots like rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria, promote nutrient mineralization and availability, produce plant growth hormones, and are antagonists of plant pests, parasites or diseases. Many of these organisms are already naturally present in the soil, although in some situations it may be beneficial to increase their populations by either inoculation or by applying various agricultural management techniques that enhance their abundance and activity.
