      Hello everyone,
      Onfarming Azolla, there is a lot of stuff to know about, its a crucial feed to livestock animals and easy to cultivate, which also cost efficient.

      About Azolla

      Azolla is a floating fern which resembles algae

      Normally Azolla is grown in paddy fields or shallow water bodies

      Multiplies quickly

      Rich in protein, essential amino acids, vitamins (vitamin A, vitamin
      B12 and beta-carotene), intermediate growth promoters and minerals
      such as calcium, phosphorus, potassium, iron, copper, magnesium

      the dry weight basis, contains from 25 to 35 percent protein, 10 to 15 percent
      minerals and 7-10 percent of the amino acids, bioactive substances and

        Livestock easily digest, because of its high protein and low lignin

        Azolla can be mixed with concentrated or can be administered directly

        Can also be fed to poultry, sheep, goats, pigs and rabbits.
        Azolla Production

        The soil of the area is first cleared of weeds and leveled

        The bricks are aligned horizontally rectangular fashion.

        A UV stabilized silpauline sheet 2mx2m size is uniformly distributed over
        bricks so as to cover the edge of the rectangle is made by

        10-15 kg of sieved soil is uniformly distributed over the pit silpauline

        Slurry made of 2 kg cow dung and 30 g of Super Phosphate mixed in 10
        liters of water is poured on the sheet. More water is poured on to raise
        the water level to about 10 cm

        About 0.5-1kg azolle terms of pure mother culture is spread seeds
        uniformly on the water, after gentle agitation of the soil and water in the Azolla

        Fresh water should be sprinkled on Azolla immediately

        Azolla inoculation to make the plants standing

        In a week's time, Azolla spreads all over the bed and develops a thick
        mat like appearance.

          Common names: Red Azolla, Ferny Azolla, the scientific name: Azolla pinnata

          What is Azolla?

          Red Azolla is a small floating fern native - one of Only six species of floating aquatic fern. It grows from 1 cm to 2.5 cm wide and is of a light green color. Its color changes to dark red when it is sunny, thus the name Red Azolla. Azolla grows in streams in dense patches, that can resemble a green or red carpet. From a distance it can be confused with Salvinia, a noxious aquatic weeds, or blue-green scum algae.

            Azolla can have adverse effects a waterway?

            The presence of Azolla in a waterway is generally beneficial. However, in cases where rivers are extremely rich in nutrients, prolific growth can be a problem. It is also possible that thick coatings, complete Azolla can cause de-oxygenation of water. This can affect organisms such as fish and other aquatic plants, and the disintegration thereof can lead to a strong odor. However, such situations this is rare because the coverage of the waterway by Azolla be almost complete for it have a negative impact on the ecosystem.

              How does a farmer manages Azolla?

              Because Azolla is a native species with many benefits to aquatic ecosystems, the Commission not automatically deleted in response to aesthetic concerns.
              The waterways are typical of aquatic environments systems in sub-tropical environments, which means that the growth of aquatic plants is a normal case subject to seasonal fluctuations. In
              the warmer months when the sun is abundant, Azolla is likely to be more prolific. The removal of Azolla can actually have negative effects impacts on a waterway. When Azolla is there to take nutrients from the water column, they become available for blue-green algae, which can flourish in environments rich in nutrients.
              These flowers are potentially toxic.

                How the community can reduce impact of the channels on nutrients?

                Everyone has a responsibility to reduce water pollution. After a few simple guidelines will help ensure our local courses remain healthy water. Clean up after pets lawns and parks and place them in a tray. Do not feed native wildlife. Provide human food for native animals can attract pests species in the system and increase fecal waste, which affects the water quality. Pets can also become dependent on human food and lose their natural ability to feed themselves. Removal of garden waste in or near water body may allow weeds to penetrate a system adding excessive nutrients. Always place garden waste in a bin or take it to the tip.
                Never wash cars or household equipment in driveway or street. This will help avoid detergents entering the storm water system. No use fertilizers in moderation and strictly according to instructions on the product.
                When starting construction or home renovations, keep the indoor building materials and install silt fences along the property borders where appropriate

                  Azolla -Methods for Cultivating

                  A mixture of 20 g of Super Phosphate and about 1 kg of cow dung should add time in 5 days to maintain rapid multiplication of Azolla and maintain daily production of 500 g

                  A micronutrient mixture containing magnesium, iron, copper, sulfur, etc., may also be added at weekly intervals to enhance the mineral content of Azolla

                  About 5 kg of bed soil should be replaced with fresh soil, once in 30 days to avoid nitrogen build up and prevent micronutrient deficiencies

                  25 to 30 percent of the water must also be replaced with fresh water, once every 10 days, to avoid the accumulation of nitrogen in the bed

                  The bed should be cleaned, water and soil replaced and new azolle
                  inoculated once every six months

                  A fresh bed has to be prepared and inoculated with a pure culture of Azolla,
                  when contaminated by parasites and diseases

                    Advantages of cultivating azolla
                    grow rapidly and fill the pit within 10 - 15 days. Therefore, 500 - 600 g Azolla can be harvested daily.

                    Can we make every day from 15th day with the help of a
                    plastic tray or sieve with holes at the bottom

                    The azolle collected should be washed with fresh water to get rid of cow dung smell,
                    Alternative entries

                    biogas suspension costs can also be used

                      The demand for milk and meat in India is creating new potential profitability of livestock farming as a occupation. Yet at the same time, there is a significant drop in forage availability. The area under forests and grasslands is decreases as the amount of various available crop residues Food, largely due to the introduction of high performance dwarf varieties. The fodder shortage is offset by commercial foods, resulting in increased costs in the meat and milk production. In addition, the commercial power supply is mixed with urea and other boosters artificial milk, it has a negative effect on milk quality and health of livestock. The search for alternatives to concentrates led us to a wonderful Azolla plant, which holds the promise of providing sustainable livestock feed. Azolla is a floating fern and belongs to the Azollaceae. Azolla hosts a symbiotic blue-green algae, Azollae Anabaena, which is responsible for setting and the assimilation of atmospheric nitrogen. Azolla, in turn, provides the carbon source and the favorable environment for growth and the growth of algae. It is this unique combination, Azolla relationship that makes a wonderful plant with large
                      protein content.

                        Nutrient content and its impact on growth Azolla is rich in protein, essential amino acids, vitamins (Vitamin A, B12 and beta-carotene vitamin), growth factor intermediates and minerals such as calcium, phosphorus, potassium, iron, copper, magnesium, etc. On a dry weight basis, it contains 25-35 percent protein, 10-15 percent minerals and 7-10 percent of amino acids, bio-active substances and bio-polymers. The carbohydrate and fat Azolla is very low. Its nutrient composition makes it a very efficient and effective supply for livestock (see Table 1). Livestock easily digestible, because of its high protein and low lignin content,
                        and they grow accustomed to. In addition, it is easy and economic growing.

                          The tests on dairy products animals showed an overall increase in milk production of about 15 percent when 1.5 to 2 kg per day Azolla were combined with regular diet. Increasing the quantity of milk product
                          was higher than would be expected based on the nutrient content azolle alone. Therefore, it is assumed that there is not just the nutrients, but also other components such as carotenoids, biopolymers, probiotics, etc., which contribute to the overall increased milk production. Azolla feeding poultry improves the weight of broilers and increases egg production layers. Azolla can also be brought to sheep, goats, pigs and rabbits. In China, the cultivation of Azolla with paddy and fish is said to have increased by 20 percent rice production and producing 30 percent of fish.

                            effective methods for mass propagation of Azolla in The farms of farmers. In our method, a body of water is made, preferably in the shade a tree, using a silpauline sheet. Is a Silpauline polyethylene sheet which is resistant to ultraviolet radiation in broad daylight. A pit of 2 x 2 x 0.2 m has widened as a first step. All corners of the pit should be at the same level so that a uniform level of the water can be maintained. The pit is covered with plastic to gunnies prevent the roots of nearby trees piercing the silpauline sheet, which is spread on the plastic gunnies. Approximately 10 to 15 kg sieved fertile soil is evenly distributed on the silpauline sheet. Porridge made of 2 kg cow dung and 30 g of Super Phosphate mixed in 10 liters of water was poured on the sheet. More water is poured on to raise the water level to about 10 cm. About 0.5 to 1 kg of fresh culture and pure Azolla is placed in the water. This will grow rapidly and fill the pit within 10 - 15 days. Accordingly, 500-600 g Azolla can be harvested daily. A mixture of 20 g of Super Phosphate and about 1 kg of cow dung
                            should be added once every 5 days to maintain fast multiplication of Azolla and maintain the daily performance of 500 g. A micronutrient mixture containing magnesium, iron, copper, sulfur, etc., may also be added at weekly intervals to improve the mineral content of Azolla

                              Azolla use as livestock feed
                              Azolla should be harvested with a plastic tray having holes
                              1 cm2 mesh to drain water. Azolla should be washed
                              get rid of the cow dung smell. Washing also contributes to separation
                              small plantlets which drain the tank. Seedlings and
                              with water in the bucket can be poured into the original channel.
                              When azolle introduction food, fresh Azolla should be mixed
                              with a commercial power supply 1: 1 ratio to feed livestock. After a
                              fortnight to feed azolle mixed with the concentrate, livestock
                              Azolla can be fed with concentrate without added. For poultry,
                              Azolla can be brought to layers and broilers.
                              Although there is no large-scale impact of pests and diseases
                              in silpauline based production system, pests and diseases
                              problems were noticed during the intensive cultivation. In case
                              severe pest attacks the best option is to empty the entire bed
                              and take a fresh bed in a different place.
                              With this method, the production cost of Azolla is less than Rs
                              0.65 per kilogram, equivalent to US $ 0.015
