Has anyone tried to grow concerned legume in the compost pit and mulch the same before flowering to increase the required strain/s of the rhizobia in the compost? Do think this techonogy can be adopted by the farmers?

For e.g. a farmers wants to grow soybean. Instead of seed coating of commercially available rhizobium, can he coat the seeds with compost (which is enriched with required strains of rhizobia-above technique) and get a good yield? Do you have any case studies on this.

Thanking you in advance for your kind attention and for the inforamtion.
