- A Bio fertilizer is a substance which contains living microorganisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Rhizobium, Azotobacter, Azospirillum and blue green algae are traditionally used as Biofertilizers.
- Ammonia occupies an unique bio-chemical position being the only inorganic form of nitrogen that is incorporated into organic linkage and thus an obligate intermediate in the utilization of other inorganic sources
