> Is it not cost-effective? A quick Googling of the literature (more general terms seems to be bioinoculant and biofertilizer) suggests exactly that. There are industrial products out there for large-scale inoculation, but manufacture, packaging, shipping, and application of bioinoculants can require rather sophisticated carriers, whether in solid, liquid, or polymer form; or engineering more easily accommodated bacteria or fungus. It seems it's still very early days for industrial-scale products, notwithstanding that the research and perhaps even some products go back decades.
