Define Biofertilizer.
‘Biofertilizer’ contains living micro-organisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Thus, biofertilizers are organisms that enrich the nutrient quality of the soil.
