Most crops are grown using azotobacter; a nitrogen-fixing free-living bacteria, as a biofertilizer. Plants are unable to directly use environmental nitrogen. Nitrogen exists in the form of N in the atmosphere. These bacterias aid plants in absorbing nitrogen from the air in the form of nitrate and ammonia. These microorganisms are used to create biofertilizers. The biofertilizer has a six-month shelf life after the date of manufacturing. The process requires locally accessible manufacturing equipment, plants and raw materials.
