Thanks for the reply sir,

I have to give different concentrations of CaNO3 as nitrogen source and look for the role of nitrogen in alleviating cadmium stress separately in each treatment and find out the best one.

Dear Iqbal,

can you use NH4NO3 instead of Ca(NO3)2 as a N-source?

Best regards

Nils

sir i am already using NH4NO3 in another experiment.

Dear Iqbal,

One option is to use KNO3 instead of CaNO3. because K+ is useful the plant.

Other oltion is Use to K2CO3 to precipitate Ca2+ as CaCO3. But you have to do this carefully, controling pH of the system.
