Dear Rajanna, the specific surface area of roots is very important and measurement is necessary as it will indicate the potentiality of the cation exchange capacity of the plant roots. It is compatible to CEC. The total charges caused out by plant roots depends on root surface area. However, water vapor adsorption isotherm measurement is more accurate to estimate plant root specific surface.

Thank you Dr Tarafdar for your enlightened views. It will be highly helpful in due course

Hello,

Actually, can you share some more information about the rhizoscanner. I am really looking forward to your reply.

Cheers.
