Hi Leo -
 
In what size area are the counts? It is goof you see bacteria, fungi and
protozoa!
 
Try something other than molasses. Gives you lots of bacteria, and you
probably want more fungi.

THX......

Elaine:

Thanks. ... I go well? or me return to begin again.
...

Now well, In my observations the average of what I see
is: more than 650 Bacteria, 20 al 30% of fungae and
protozoon (my microscope does not have good
resolution) per field, but I continue improving the
elaboration of the tea.

I watch is the form of addition of the materials
mainly the molasses and the algae and clearly that the
compost be seen colonized of fungae


Salu2

english....

PS: Greetings to Twila and Ted
