Solution

Azolla is a biofertilizer. It contains nitrogen fixing cyanobacterium Anabaena as symbiont. A part of the fixed nitrogen directly passes into paddy field while the rest is made available to the field after death of Azolla. It therefore, enriches the field with nitrogen as well as organic matter. On decomposition, organic matter releases minerals. It also maintains health of the soil. All these help improve the yield of crop. The quality of the product is also improved due to absence of chemical fertilizers.
