Hi
Azolla an aquatic fern that hosts the blue green algae – Anabaena azollae, seems to hold the solution for this gloomy situation. For decades Azolla has been used as bio-fertilizer in many paddy growing countries including India, Vietnam and Philippines.
Nevertheless it’s potential as cattle feed has been discovered only recently. VK-NARDEP (Vivekananda Kendra’s Natural Resources Development Project) Technology Resource Centre has made a detailed study on this dimension of Azolla and has also developed a cost-effective technology to harness fully this dimension of Azolla which benefits mainly the marginal dairy farmers.
