growing nitrogen bacteria

[microman]

HI,

There is a shortage of inoculant for chickpeas this year, and I'll be seeding next week. I have one bag of inoculant, which I'd like to grow more from. The type is Rhizobium spp. for chickpea.

I have growing other bacterias and fungi using molasses, water and air bubblers. I read it was difficult to reproduce this variety, for a reason that I didn't understand.

What procedures would be recommended, to increase my supply. Thank you.

I am in a hurry, and appologize for not taking the time to read more of the forum, if this has been covered.
