As the material of the structure doesn’t have any impact on azolla growth, I didn’t considered about material of structure. The thing only I thought about the containts which I have to add to water which helps azolla to grow. The contens are listed below:

Material selection

Calculations:

 

Content	Quantity	Cost (Rs/kg)
Soil	10 kg	3
SSP	270 gm	10
Mineral mixture	90 gm	30
Slurry	30 lit	420
Water	2000 lit	12500

 

The above listed contents are require for area of 36.4 m^2.

Total area of dome = 38.4 m²

Area which using for Azolla growth 36.4 m²

I also studied the soil testing in order to know the organic matters from soil which will help me tfor selection of contents and their quantity.
