Abstract
Nitrogen is used for various applications in addition to the agriculture production. Biological nitrogen harvesting from aquatic /sea bird dropping, known as ‘Guano’ opens new door for capturing nitrogen from the sea or aquatic ecosystems and rearing birds close to the fishery ponds/terrestrial water bodies. The present study takes account of various innovative developments that have been brought in management of nitrogen cycle and brings further advancement in the biological nitrogen harvesting from the aquatic ecosystems that will go eco-friendly long way in environmental improvement promotions. Thus, the new ancillary natural nitrogen producing source would lessen problem caused by pollution of water in the rivers, lakes and ocean etc. on one hand and become source of developing enterprises of immense applications for generating employment and income, on the other. The biological harvesting of nitrogen will provide avenues for linking hydro-ecosystem to the terrestrial ecosystem through birds for transferring nitrogen from hydro ecosystem to terrestrial eco-system. The up-scaling of the research for assessing the content of iodine from the guano will make further vast resource of biological iodine harvesting and bring its use in eradicating wide spread iodine deficiencies, goitre related hazards to human health.
