Azolla cultivation enhances soil fertility through nitrogen fixation and provides a high-protein feed source for livestock and poultry. It contributes to weed control when integrated into rice paddies, reducing the need for chemical herbicides. Azolla also serves as a biofertilizer, improving crop yields. Additionally, it helps in maintaining water quality by absorbing heavy metals and other pollutants. The fast-growing fern can be harvested frequently, ensuring a sustainable supply of organic matter.
