Butch, you are concerned about the rizosphere, where all those great
nitrogen fixing bacteria make the nitrogen available to the tomato
plants.  The problem is, all the other plants seem to be doing well.
So, the question is what to do about the soil in the root zone around
the tomatoes and how might tea, specifically help? Right?

One way to turn off some of the bacteria that make the nitrogen
available in this zone is to change the pH--lower it, so that the
environment is not so friendly to them. This could be accomplished with
a tea of a lower pH (how low can  you go?) or one that has fungal
dominance, something that is awfully hard to achieve.

Of course, depending on the number of tomatoes, it might be easier to
replace the soil in the hole the plant goes into!

Cheers,

Jeff
