Which microorganisms enrich the soil with nutrients and use micro-organisms to enhance plant growth and bloom?
Biofertilizers are microorganisms that add to the nutrient quality of the soil. Bacteria, fungi, and algae are some of the beneficial microorganisms that help in improving the fertility of the soil. Biofertilizers are classified as: Free-living nitrogen-fixing bacteria like Azotobacter, and Rhodospirillum. Biofertilizers are microorganisms that enhance nutrient availability to plants, contributing to plant nutrition either by facilitating nutrient uptake or by increasing primary nutrient availability in the rhizosphere. To access these nutrients, plants are dependent on the growth of soil microbes such as bacteria and fungi, which possess the metabolic machinery to depolymerize and mineralize organic forms of N, P, and S. Microbes improve soil fertility and enhance nutrient absorption and utilization of MPs by decomposing plant residues, increasing organic matter content and promoting nutrient availability. In order to be of greatest benefit to our plants, the soil must be nutrient-rich and filled with living organisms. Such a process of enrichment of soil with nutrients is called as soil replenishment. Beneficial microorganisms include those that create symbiotic associations with plant roots (rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria), promote nutrient mineralization and availability, produce plant growth hormones, and are antagonists of plant pests, parasites or diseases (biocontrol agents). Rhizosphere fungal and bacterial community can harbor beneficial organisms known as PGPM. These organisms have the ability to colonize plant roots providing benefits to their hosts, by modulating the production of phytohormones, increasing the availability of soil nutrients, and the resistance against pathogens. Due to their close proximity to plant roots, soil microbes significantly affect soil and crop health. Some of the activities they perform include nitrogen-fixation, phosphorus solubilization, suppression of pests and pathogens, improvement of plant stress, and decomposition that leads to soil aggregation.
A diverse community of microorganisms plays a crucial role in enriching soil with nutrients and enhancing plant growth and bloom. These microorganisms contribute to various essential soil processes, including:
By fostering a diverse and healthy microbial community in the soil, we can promote sustainable agriculture practices, enhance crop productivity, and improve overall soil health.
Beneficial microorganisms include those that create symbiotic associations with plant roots (rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria), promote nutrient mineralization and availability, produce plant growth hormones, and are antagonists of plant pests, parasites or diseases (biocontrol agents).To access these nutrients, plants are dependent on the growth of soil microbes such as bacteria and fungi, which possess the metabolic machinery to depolymerize and mineralize organic forms of N, P, and S. PGPMs, including plant growth-promoting bacteria (PGPB), arbuscular mycorrhizal fungi (AMF), and rhizobia, increase the production of biomass in plants through synthesizing hormones, fixing nitrogen, and solubilizing phosphate and potassium. Rhizosphere fungal and bacterial community can harbor beneficial organisms known as PGPM. These organisms have the ability to colonize plant roots providing benefits to their hosts, by modulating the production of phytohormones, increasing the availability of soil nutrients, and the resistance against pathogens. Microbes improve soil fertility and enhance nutrient absorption and utilization of MPs by decomposing plant residues, increasing organic matter content and promoting nutrient availability. By far, the most numerous microbes in soil are bacteria, which have just one cell. Also abundant are fungi, which produce long, slender strings of cells called filaments, or hyphae. The actinomycetes are in-between these two organisms. They are advanced bacteria that can form branches like fungi. Due to their close proximity to plant roots, soil microbes significantly affect soil and crop health. Some of the activities they perform include nitrogen-fixation, phosphorus solubilization, suppression of pests and pathogens, improvement of plant stress, and decomposition that leads to soil aggregation.
