Hi
Azolla is produced as follows (NARDEP) Under the shadow of tree, dig 222 m pit then clean edges and base of pit should be kept in a level. Put plastic paper in pit then place silpaulin sheet above the plastic sheet. Put 10 – 15 kg fine soil after that spray slurry which contains 2kg cow dung& 30gm super phosphate in 10 liters of water. Add water o make the level of water of 10c.m..Then add 0.5-1kg of fresh Pure Azolla culture. After 10-15 days there is uniform growth of Azolla .afterward from each bed 500-600 gms of Azolla can be procured .Regularly after each 5days 1kg of Dung and 20gms of super phosphate to be added in each bed. Mixture of Picrolutopa also added at each week. It has necessary to harvest 200gms of Azolla per week. Also temperature of surrounding should not go above 25C,kee the water pH 5.5 -7 .At each month,5kg soil should be replaced and at the age of six month ,these bed should totally replaced with new beds. During this procedure, Azolla caught smell of cow dung and so for that animal can not eat Azolla when it fed solely. So what, care is taken to wash harvested Azolla then mix small amount in concentrates of animals initially. After animal has conditioned with smell of Azolla you can put Azolla solely as feed of cattle.azolla should be fed in the proportion of 1:1 as cattle feed (1.5 to 2 kg).
Azolla is one of the waterborne blue green algae or fern which is mainly used as organic fertilizer in rice field in many part of world.Azolla has micro leaves, fibrous roots as body parts & these small leaves are greenish from above & whitish in color below. However the anatomy of leaves has concern, these leaves have small vacuum in upper part which consist of Blue green algae called as “ANABINA AZOLLY” which fixes nitrogen from surrounding environment.
