The world wide increase in human population raises a big threat to the food security of each people as the land for agriculture is limited and even getting reduced with time. Therefore, it is essential that agricultural productivity should be enhanced significantly within the next few decades to meet the large demand of food by emerging population. Not to mention, too much dependence on chemical fertilizers for more crop productions inevitably damages both environmental ecology and human health with great severity. Exploitation of microbes as biofertilizers is considered to some extent an alternative to chemical fertilizers in agricultural sector due to their extensive potentiality in enhancing crop production and food safety. It has been observed that some microorganisms including plant growth promoting bacteria, fungi, Cyanobacteria, etc. have showed biofertilizer-like activities in the agricultural sector. Extensive works on biofertilizers have revealed their capability of providing required nutrients to the crop in sufficient amounts that resulted in the enhancement of crop. There are 17 essential elements required for proper growth and development of the plant. Among them, nitrogen (N), phosphorous (P), and potassium (K) are needed in relatively large quantities . Several microorganisms are commonly used as biofertilizers including nitrogen-fixing soil bacteria and cyanobacteria, phosphate-solubilizing bacteria, used along with the combination of molds and fungi. Similarly, phytohormone producing bacteria are also used in biofertilizer formulation. They provide the growth- promoting substances like indole acetic acid (IAA), amino acids, and vitamins to the plant and improve the productivity and fertility of the soil while maintaining the crop yield. The present review elucidates various mechanisms that have been exerted by biofertilizers in order to promote plant growth and also provides protection against different plant pathogens. The aim of this review is to discuss the important roles and applications of biofertilizers in different sectors including agriculture, bioremediation, and especially for Sustainable Agriculture & Ecology.

In this review, the most important microorganisms used as biofertilizers are explained along with their mechanism of action. It is also observed that the inoculation of two dif erent types of biofertilizers increases the yield of crops more sig-nificantly than the single biofertilizer or solo chemical fertilizer inoculation. The increasingdemand for biofertilizers reflects an eco-friendly and sustainable agriculture system in thefuture. However, knowledge about soil properties, field environment, and host specificity of strains is mandatory for the successful production and application of biofertilizers.Recent advances in the field of molecular biology, biotechnology, genetic engineering, mi-crobial taxonomy, and nanotechnology have played a significant role in the production of biofertilizers with improved ef iciency, higher competitive ability, and multiple functionali-ties. Biofertilizers can maintain crop productivity with low environmental impact and can be an ef ective substitute for chemical fertilizers. Research ef orts are still required in this field to explore and identify soil-specific strains, to gain further insights into biofertilizer composition, and to improve the existing strains using biotechnological methods.
