Biofertilizers need of tomorrow

Bio-fertilizers add nutrients through the natural processes of nitrogen fixation solubilizing phosphorus and stimulating plant growth through the synthesis of growth-promoting substances. Bio-fertilizers can be expected to reduce the use of chemical fertilizers and pesticides. The microorganisms in bio-fertilizers restore the soil's natural nutrient cycle and build soil organic matter. Through the use of bio-fertilizers healthy plants can be grown while enhancing the sustainability and the health of the soil. Since they play several roles a preferred scientific term for such beneficial bacteria is plant-growth promoting rhizobacteria (PGPR). Therefore they are extremely advantageous in enriching soil fertility and fulfilling plant nutrient requirements by supplying the organic nutrients through microorganism and their byproducts. Hence bio-fertilizers do not contain any chemicals which are harmful to the living soil. Bio-fertilizers provide eco-friendly organic agro-input. Bio-fertilizers such as Rhizobium Azotobacter Azospirilium and blue green algae (BGA) have been in use a long time.
