Hi Edward,
I'm sure you are absolutely right in what you say. My intent with this
sentence, "Sugar alone can bloom the soil micro-flora." was to point out
that microorganisms in soil thrive on complex carbohydrates for energy and
nutrients, not on sun, water, and C HOPKINS CaFé Mgr plant nutrients, like
most plants need to thrive.
Soil microorganisms are not like plants. The nutrients for one are not the
same as for the other. There is perhaps some overlap, but the relative
amounts and uses of the nutrients are different. The organisms differ in
two very basic ways; soil microbes do not, in general, perform
photosynthesis and plants do not, in general, decompose plant nutrients from
the soil or the soil organic matter in the soil, all by themselves. These
two different sets of organisms actually do need to rely on one another for
the mutual continued existence. Plants need nutrients that microbes can get
from the soil. Microbes need carbohydrates, that plants build with
photosynthesis. They have a symbiotic relationship which assures their
mutual preservation.
However litigious and exacting as one my be, I do not believe I've made any
misstatements here ?
Regards,
SKB

NOTICE on lab test, used by soil science researchers - sugar alone can
bloom the soil micro-flora:
This is a very big difference to make micro scale lab tests in sterile in
vitro conditions with sugar or few nutrients (which results certainly not
true for in vivo conditions), or to make scale up in vivo tests under real
conditions. I develop soil microbiological adaptations into different
alternative carbon carriers, to develop solid state fermentation and
formulation technology for the horticultural industry. In this context
sugar and molasse is often used as nutrient, but not only sugar. We have
tests sites in The Netherlands, Germany, Italy, Israel and Hungary under
different soil and climatic conditions, and all tests confirming that a
complex nutrient strategy and scale up conditions are absolutely important
to reach economical output for the cultivations.

Hi Brian,
Sugar alone can bloom the soil micro-flora. There is a lab test, used by
soil science researchers that makes use of this. It increases soil
respiration" rates, which is an indication of increased living microorganism
activity. Dr. A.D. Karve (in this group), from India, has claimed that this
is very important. Even to the point where "sugar" is the sole amendment,
no fertilizers required. But, sugar with charcoal? Now that could be a
different, perhaps more long-lived, effect than charcoal alone. Maybe the
charcoal can buffer the soil pH, increasing Cation Exchange Capacity? Maybe
the carbon in the charcoal can catalyze the decomposition of organic matter
into plant available nutrients? Maybe the porous nature of the charcoal
holds more water and provides a "safe haven" for soil microorganisms to grow
into and stay, set up shop as it were, etc?
These are all, I believe, very "fertile groud" (pun intended) for Terra
Preta research. It does look promising, so far. So, we just need to get
more people excited about doing this kind of research.
Regards,
SKB

Sugar is the energy currency of soil flora. This makes sense because
autotrophs utilize the sun and ofc...its dark down there so its not like
they can fix their own energy from the sun. I would also suspect what PurNrg
is implying...that residual sugars increase soil flora but only as a temp.
shot in the arm. This is only a short term shot and not a long term affect.

This would lead me to wonder whether there was not a lot of residual sugar
in the charcoal from said syrup, which would definitely be a different thing
than JUST charcoal. As we've read earlier in this discussion, the sugar
promotes a massive, temporary bloom all all sorts of soil critters. This
bloom and it's associated activities could well be responsible for using up
easily available soil nutrients, making them less available to plants in an
immediate sense. Then, when the sugar has been consumed, there is the die
off of many of the extra critters and their decomposition releases all those
nutrients again in a form readily available to the plants.
