Azolla filiculoides
Sir,
Azolla [Azolla filiculoides] is a aquatic fern, is used for nitrogen fixing also. Now this is widely used as food supplement in many countries. Also used as the food supplement to the cattle and poultry feeds. A high nutrient high fibrous food leads to eradicate the free radicals in the body of both human beings as well as animals[including birds]. I can supply the seeds free of cost. The planting so easy. A temporary tank with silpaulin sheet will be sufficient. You can use it for human being, cow, chicken, goat, sheep, buffalo etc. Duck weed is also used for the same purpose. In Sirsi, The agriculture centre for arecanut and pepper will be able to help you. Contact Dr. Lokesh
