I am designing a module on microbial ecology for an intro micro class. I
would like to know some reasonable viable counts of soil bacteria in
agricultural soils. The particular species I am interested in are:
Rhizobium/Bradyrhizobium, Azotobacter, Nitrosomonas, Nitrobacter, and
Paracoccus denitrificans. Exact numbers are not required, I just want to
be in the right neighborhood.

thanks very much
