The formost researcher on the plant growth promoting bacteria Azospirillum has posted all of his work for our enjoyment.

For a fast primer on the potential of this bacteria look at pages 38-57 of the this link:

Here is all of his work, very good stuff.

The researcher was catching Azospirillum in the Ohio countryside, an amusing image...

Trapping Azospirillum and Diazotrophs from the Countryside
Air by a Moving Trap
A. brasilense was trapped from the farmland air of central Ohio by moving
traps from spring until autumn (5-8 cfu/318 cm2 surface medium). Trapping of
Azospirillum was possible on secondary, low-traffic country roads and impossible
on the major, heavily trafficked highways crossing the same farmland
areas. Trapping of A. lipoferum followed the trapping pattern of A. brasilense
(1-6 cfu). Neither Azospirillum species was trapped during a winter sampling,
taken under low temperatures and snow cover (Jan. 27, 1989). Higher numbers
of other diazotrophs (confirmed by ARA) were trapped on the farmland roads
(11-28 cfu), whereas lower numbers of diazotrophs were trapped on the major
highways and in the winter sampling (Table 5).

I'm a big believer in good soil biology but I've never seen a trophy for "heaviest bacillus". I sell PHC products so I do practice what I preach. ;o)

There's a first time for everything though.
