Mike, based on my experience this succesion to fungal dominance is governed
strongly by the organic matter levels present in the soil and in particular the
the more complex carbs such as hemi-cellulose and lignin - stuff that the
active fungi can really get thier teeth stuck into. I did a number of
applications on my vineyard (with some excellent SFI numbers) last year where
some rows were mulched and other were not, the unmulched rows had little visible
fungi whereas the mulched rows were loaded with the stuff. If you supply the
accomodation the fungi will check in for an extended stay. Although the area has
been subject to biological methods for two years prior, it would of been your
typical high bacterial paddock before that.

Subject: [compost_tea] Molasses
Elaine,
I have a situation in Strawberries where we will
be using AACT and other materials to restore the food web.
About 50 tonne per ha foul manure (including saw
dust) plus super phos and other chemical ferts have been used as well as lime
and other inputs preplant it was then gassed (methyl bromide). Plastic layed
and planted.
Full soil food web analysis has been done and I
am waiting for the results.
I expect the results to come back showing a lack
in the fungal biomass as well as bacterial.
We will be using Molasses, humic acid and
AACT to restore the web.
Am I right in saying that the soil must go
through succession that is, it must
first become
bacterial dominated before it can then progress to fungal dominated?
Thus using sufficient rates of molasses to cause
a large increase in Beneficial bacteria and then using humic acid as
well as molasses to continue the succesion towards fungal dominated (always
using AACT as the inoculant) Is this the way to go??.
I note that in the past we have said that
Molasses grows bacteria not fungi however we now know that Molasses will also
grow great fungi in higher concentrations. I have seen this in compost will
the same thing happen in the soil??
Molasses is a great product to use in drip lines
(compared to other organic products eg fish) and is reasonably priced
hence my interest in it.
We will test the food web later in the
season to see what changes have occured so it will be
interesting.
Regards Mike Harvey
