ABSTRACT
Azolla is a rapidly growing free-floating freshwater fern that fixes atmospheric nitrogen by establishing a symbiotic association with a prokaryotic cyanobacterium, Anabaena azollae. For lowland rice fields, it is a cost-effective, eco-friendly biofertilizer. It increases the rapid mineralization of nitrogen, increases the physical and chemical properties of the soil, and increases soil microbial activity in water-logged soil. Azolla is known as a good practice for the conservation of soil fertility and productivity of crops.
