When applied to seeds, plant surfaces, or soil, Biofertilizers are substances containing living microorganisms that colonise the rhizosphere or interior of the plant and encourage growth by boosting the supply or availability of primary nutrients to the host plant. In biofertilizers, nutrients are provided to plants through natural processes such nitrogen fixation, phosphorus solubilization, and the creation of chemicals that promote growth.Natural fertilisers called biofertilizers include microbial life. Blue-green algae, rhizobium, azotobacter, and azospirillum are a few of the typical biofertilizers (BGA).
They are used on soil and seeds, and the microorganisms that colonise the plant's rhizosphere boost the availability of essential nutrients. Additionally, they use organic methods for fixing nitrogen, phosphorus solubilization, and growth-stimulating chemicals, which all work together to promote plant growth. Biofertilizers improve the sustainability and health of the soil by increasing organic matter and restoring the soil's natural nutrient cycle in comparison to artificial fertilisers. They are also often utilised in organic agricultural methods because they are economical and environmentally friendly.
