The tea concentrates the quantity and extends the application of the
microorganisms responsible for the biological foundations of
agriculture - in itself, an organism based activity. The products
discussed are simply two different applications of that.

So while I agree that both applications are complementary, what you
suggest prevents one of them from fulfilling it's function.

As Elaine has often said, much remains to be learned about the
multiple benefits provided by soil microorganisms.

Nine years ago I purchased a copy of "Investigaciones Hoy", a
magazine published by Mexico's Instituto Politecnico Nacional
(IPN), which contained an article describing seven fungi and six
bacteria that produce Auxins, Giberelines, Cytokinins, Abscisic Acid
and Ethylenes (all of which are considered phyto-hormones, as well
as the actions of each on plants. (I am translating from the Spanish
forms of these words so some may be misspelled in English).

That same year I searched through bio-medical databases for
additional information on some of these organisms and was pleased to
confirm that substances with antibiotic activity against pathogens
are also produced (not surprising, considering that antibiotics were
developed from soil microorganisms), by at least some of those
organisms mentioned in the IPN article.

So if you want to inoculate a plants roots against pathogens that
attack those roots, adding compost tea containing the appropriate
beneficial microorganisms to the soil around those roots might be
wise. But that would be less helpful if you're trying to prevent the
infestation or infection of other tissues.

Don't stop thinking. (I know you won't).

As I understand it, compost tea rapidly concentrates and permits the
application of the same microorganisms found in the compost you make
it from to the rest of the plant.

In order to determine your best course of action, you need to know
what you should be guarding against. If your present regimen has
been sufficient with respect to disease prevention, maybe you don't
need to apply compost tea.

Elaine promotes the need for performing a kind of soil analysis
that's not readily available. She's doing that in her Oregon lab
(north of your location), but whether you want or need to go that
route is another matter. It *would* tell you what you have in your
soil, microbiologically speaking.

In addition to knowing what your potential pathogens are and which
tissues they attack, knowing which microorganisms are likely to be
effective against them and how to make sure they are present in your
soil and on your plant -if that's where you need them- would be

Is this kind of information even available? Maybe some of sanet's
academics can answer that.

As things stand, a generalized belief in the power of the diversity,
presence and activity of the kind of microorganisms you obtain by
brewing aerobic compost tea to stimulate growth and prevent disease
is probably driving most of those using it.

The question is: Is that enough? Or should we know more?

If so: Why is so much funding channeled toward a research agenda
that focuses on reinventing (subverting, actually) an evolutionary
path that took millions of years to create?

Why are aren't the issues mentioned above being addressed instead?

Are we going to study, understand and work *with* natural biological
systems or continue to labor in bad faith - against the systems that
gave rise to ourselves and life on earth as we know it?

Or is that message too hard to package and sell?
