10 Vital Roles of Algae in relation to Agriculture

                   Central Roles of Algae on the Planet

                 Phycologist says life is impossible without aquatic photosynthetic algae that belongs from kingdom Protista. There is a great variation in size from micromonas algae to 200 feet kelps, in terms of number of cells from one cell to millions of cells. There are following major roles that plays algae on planet earth:

1. It is reported fact about 50% oxygen of the available oxygen in atmosphere for respiration comes from algae.
2. Algae are subjected as a green manure for the field to enhance the soil health. There are many reported species which includes Gracillaria and Sargassum.
3. Some algae species as a biofertilizers that improve soil health by fixing nitrogen from the atmosphere directly like Nostoc, Spirulina etc.
4. In different regions of the world some algae species are widely used as source of reclamation of saline soil like some blue green algae.
5. In livestock point of view algae are the rich source of fodders for the farm animals. These includes Laminaria and Fucus.
6. Vegetative animals (herbivores) in sea life like fishes, sea star and worms etc mainly rely on algae as a main food source.
7. Some algae species of micro-algae like Botryococcus can be the alternative energy source for fuel in the future. High oil recovery, less carbon dioxide and less time consuming oil will be the future of the world.
8. Algae fix carbon dioxide efficiently about 40% of all the planet carbon dioxide. It directly clean environment and lowers global warming.
9. Some algae species are used as a food for human population which includes Chlorella, Sargassum, and Spirullina etc. These are rich source of carbohydrates, proteins, carbohydrates and vitamins etc.
10.  Agar-agar is used in culture media for energy sources therefore it is main component of green biotechnology lab.

         Algae are some times known as plants primitive forms have great relationship with agriculture in these days and playing vital role for environment stability. Algae can play important role to uplift agricultural sector by various forms like fertilizers,food source, soil reclamation and health improvement and many other forms etc. It is recommended that to screen the species which are helpful for agricultural or industrial point of view to uplift the living standard of human beings.
