Just to add: most of the above does also apply to the mycchorizal fungi
question, for similar reasons: while we don't have humans as the test
subjects, we do have huge numbers of variables that we so far don't
well understand: results might well vary depending on the strain of
fungi; other factors varying the fungi themselves; the crop and
particular variety of crop inoculated; the soils being inoculated (soil
type, previous management factors affecting the soil); the overall
climate; the specific weather during the study; the pre-existing
microbial and macrobial life in the soil; the timing of inoculation
versus the growth stage of the crop and the time of year; the
particular improvement being desired by the farmer (better yield?
better flavor? better nutritional value? long term survival of the
Until recently, as I understand it, very little work has been done in
regards to the various organisms that can be found living in soil, and
even less on the interrelations among this huge number of highly
variable organisms and among them and likely crop plants. It's a huge
and complicated field. The work needs to be done; but expecting fast
and clear results, at least past the stage of "this is how you can kill
everything in the top 6" of your field" or "inoculating your peas with
rhizobia is probably useful", is unreasonable. People claiming that
they have definite and clear answers should be regarded with caution,
unless they're making it clear they're addressing a very limited area
of the subject; and probably even then, as one of the things we don't
know is to what extent what appears to be such limited area are
actually affected by factors outside those limits.
Whether the work with mycchorizal fungi has approached the level of
peas and rhizobia isn't entirely clear to me -- it may have done so
with some species in some soils under some growing conditions. This
wouldn't mean that such information would automatically transfer to all
species in all soils.
Now I really need to go get something else done, sorry about the run-on
