Biological fertilizers are microbial inoculants which can be generally defined as preparations containing living cells or active strain efficiently fix nitrogen, phosphate solvent, and cellulolytic microorganisms, etc.
In contrast to chemical fertilizers, biofertilizer is a viable microorganism that is not a source of nutrients for the plants but provides assistance in accessing the availability of nutrients in the rhizosphere. Some microorganisms are commonly used as a biological fertilizer including nitrogen soil bacteria and AM fungi.

Similarly, phytohormone (auxin) -producing cellulolytic bacteria and microorganisms are also used as a biological fertilizer formulation.
Biofertilizers were cheap, renewable source of plant nutrients.
It is a strain of beneficial soil microorganisms are cultured and packed in a suitable carrier in the laboratory.
More recently, biofertilizers are gaining momentum as a great advantage as the maintenance of soil health and the reduction of environmental pollution by the use of chemicals in agriculture.
Increased crop yields depend on the type of fertilizer used to increase the nutrients essential for plant growth and development.
For optimal plant growth, it requires nutrients in sufficient quantities and balanced but on the ground, only a fraction of the nutrients are released each year through biological or chemical processes. Therefore, the purpose of fertilizer used is to supplement the nutrients already in the soil.
Biological fertilizers are artificially maintained cultures of microorganisms that can be used as a soil or soil microbial inoculants to improve the fertility and productivity of crops and soil.
