Azolla is one of the fastest growing plants in the world.It can double its biomass in just 2 days under favourable conditions.Once the azolla covers the entire water surface,the azolla plants start growing over each other and form a thick mat.Enough azolla is harvested so that only a thin layer of azolla remains in the pond.IF the water contains enough nutrients ,the azolla grows again to form a thick mat ,this process can be continued till the water runs out of nutrients.For best possible results add nutrients after every harvest.
Since azolla grows so fast it becomes a good input for biomass renewable energy solutions and also as a animal feed option because azolla has nearly 25% protein by dry weight.

Rice fields are kept flooded to prevent weeds from growing,rice plants actually do not need the water flooded conditions.
Azolla can be grown on the water surface in between the rice plants.It covers the water surface and reduces water evaporation especially under irrigated rice.
Azolla has the bacterium anabaena azollae that fixes nitrogen so less N fertiliser is required, plus the dead azolla adds to soil organic matter once it dies and best part is unlike compost or other fertiliser it does not need to be purchased, handled and spread with specialty equipment costing time and money.It grows exactly were it is required i.e. in the field
