Yes, there is talk about that and I have seen some microbiology studies that show some soils are pretty "dead,"

The main point is the inoculants in the last 18 years don't have the staying power in the soil the old strains had back in the 70's and need to be reintroduced every year. The tests I have done in 18 years shows they pay and are a great return on investment.

You could have live rhizobia in your fields and probably do, but it might be a strain from the 70's that will really come to life when it fights for a place to compete on the nodules of your soybean crop with a new strain you plant with the seed next year.

Inoculants are a sound investment every year as far as I am concerned.
