Cyanobacteria are the precious bio-source for potential application in sustainable agriculture. Cyanobacteria or blue-green algae hold biological nitrogen fixation properties through which they fix atmospheric nitrogen to reduced forms. These algae fix nitrogen either as a free-living form or in symbiotic associations. More than 20 kg of N ha−1 and organic matter available in soil are fixed by cyanobacteria. The easily available and less expensive eco-friendly cyanobacterial fertilizers control the nitrogen deficiency in soil, aeration capacity, and water holding capacity of the soil. The high cost of chemical nitrogen fertilizers replaces with the cost-effective cyanobacterial fertilizers. The economically feasible methods of cultivation enabled the successful large-scale production of cyanobacterial fertilizer. The initial production methods of cyanobacterial fertilizers were easy and inexpensive and widely adopted by the farmers in their fields. There are open and closed system cultivation methods using sunlight and artificial light. The effective application of cyanobacterial biofertilizers has reduced the burden of economically weak farmers to substitute expensive chemical nitrogen fertilizers. Nitrogen biofertilizers are the most putative fertilizers in the Asia-pacific biofertilizer market and received huge attention from consumers. Recently, there has been an enormous demand for cyanobacterial biofertilizers in Asia, especially the Indian subcontinent, for extensive application in the paddy fields. The deteriorated soil health in India accelerated the translation of cyanobacterial biofertilizer technology from the laboratory to small-scale, large-scale, and commercial sectors. This chapter focuses on the mass multiplication, production cost analysis, and marketing of cyanobacterial biofertilizers.
