What does Azolla look like?
Azolla is often misidentified as duckweed (Lemna spp), another common small floating aquatic plant. Azolla is initially green, like duckweed, but soon turns a red or brown color. This coloration is caused by Azolla’s association with a nitrogen-fixing cyanobactrium-Anabeana azollae.
What is the best fertilizer for Azolla?
Fertilize Azolla with 2.2 kg Phosphorus (P)/ha every 5 d, 4 kg K/ha every 10 d, and/or 500−1000 kg/ha farmyard manure every 5−10 d. If chemical fertilizers are unavailable, ash is substituted.
Does Azolla need sunlight?
Azolla grows best in full to partial shade (25-50% of full sunlight ). Growth decreases quickly under heavy shade (lower than 1500 lux) and more than 50% of full sunlight reduces photosynthesis.
How do you increase Azolla growth?
Important tips for growing Azolla Sulfur etc., at weekly intervals, to enhance the mineral content of Azolla. Replace 25 to 30% old water with fresh water once in 10 days; it helps prevent nitrogen build up in the pond. Replace complete water and soil at least once in six months, and then add Fresh Azolla seeds.
Is Azolla good for chicken?
Poultry and in particular ducks and chickens can be raised on a diet including fresh azolla. It has long been recognized as a feed for wildfowl in the USA and for domesticated ducks in China and it has been used as a feed to domestic fowl in Vietnam (Dao & Tran, 1966).

Dry and fresh Azolla pinnata were evaluated as feed ingredients for fingerling and adult Nile tilapia, Oreochromis niloticus (L.). Furthermore, adult tilapia fed fresh Azolla started losing weight from the 7th week. Fish fed fresh Azolla had significantly higher moisture content than those fed formulated diets.
Is Azolla good for fish?
Azolla pinnata as a fresh feed, in combination with a food level of natural feeding, can be beneficial to fish production . Therefore, it could be an excellent inexpensive feed for B. gonionotus. Dried and processed Azolla have been tested as feed ingredient in a number of fish species (e.g., tilapia, carp, etc.)
Does Azolla produce oxygen?
Azolla with a higher photosynthetic capacity (Wagner 1997) might release sufficient oxygen into the standing water and soil (Bharati et al.
How do you control Azolla?
Azolla can be controlled by rakeing or skimming it off the pond’s surface.
Is Azolla a bacteria?
Azolla and the blue-green alga Anabaena azollae maintain a symbiotic relationship: the alga provides nitrogen to the fern, and the fern provides a habitat for the alga. These photosynthetic bacteria have the ability to transform atmospheric nitrogen into nitrate fertilizer.
