ABSTRACT
Biofertilizers are natural fertilizers that are microbial inoculants of bacteria, algae, and fungi which may help biological nitrogen fixation for the benefit of plants. They help build up the soil microflora and thereby the soil health. Biofertilizers also include organic fertilizers. Different biofertilizers have various functions and roles in targeted plants. Nitrogen biofertilizers form an association with plant roots. They penetrate in the root cortex and spread around the roots of the plant. As the name indicates, they possess sac-like structures called vesicules which store phosphorus as phospholipids. The other structure, called the arbuscule, helps bring distant nutrients to the vesicules and roots. The information acquired from the literature thus assists the physiological bases of biofertilizers towards supportable agribusiness in decreasing issues related to the utilization of composts with synthetic compounds.
