Ajola Grass
It seems like there might be a typo or a mix-up in the name you provided. It's possible you're referring to "Azolla," a type of aquatic fern rather than "Ajola grass." If you meant Azolla, here's some information:
Azolla is a genus of small, free-floating aquatic ferns that grow on the surface of still water bodies such as ponds, lakes, and rice paddies. It is commonly known as "mosquito fern" or "duckweed fern."
Azolla has a symbiotic relationship with a nitrogen-fixing cyanobacterium, Anabaena azollae, which allows it to convert atmospheric nitrogen into a form that is usable by plants. This ability makes Azolla a valuable natural fertilizer in rice paddies and other agricultural systems.
In addition to its role as a nitrogen fixer, Azolla is also used as a livestock feed, especially for poultry and fish, due to its high protein content. It is also considered a useful biofertilizer and is used in integrated rice-fish farming systems to improve soil fertility and productivity.
