i have a serious need and opportunity for aquaponic experimenters to
collaborate in developing new technology in tree culture.
the champion tree project harvests cuttings from the largest registered
specimen of each tree species. we propagate these cuttings into new sapling
trees that contain the complete and pure genetics of the mother tree. we
plant groves of these cloned saplings as archival living libraries at
protected, reserved locations such as colleges, universities, parks,
botanical gardens, etc. these patings become genetic preserves of this
biggest and best of the sylvan gene poool. thus, when the parent tree dies,
we still have its genetics available for research and reforestation.
since 1949 american forests in washington, dc has kept the national register
of big trees. the 1998 edition list 825 trees in 687 varieties with a
recognized national champpion. most states maintain their own state big
tree list from which the national register is compiled.
while the national register is 50 years old, our preservation effort is only
three years old. our michigan chapter has propagated seven of its 57
national champion trees: red maple, sugar maple, norway maple, white ash,
red ash, green ash, american elm. our florida chapter has cloned ten of its
156 national champions: green buttonwood, silver buttonwood, wax myrtle,
crape myrtle, live oak, baldcypress, shaving brush, dahoon holly, florida
privet, and magnolia. here in new york we have our national champion white
ash in propagation; imagine an ash tree 23.5 feet in circumference and 97
feet tall.
we have a tentative beginning for a website at the URL in my trailer.
currently we use two propagation methods to turn cuttings into clones.
schmidt's nursery in oregon grafts buds onto two year old rootstocks to
jumpstart new saplings. our florida chapter roots cuttings to avoid
uncertainties, pitfalls and weaknesses inherent in grafting. for speed and
commercial volume, bud grafting is preferred, but to serious and true
genetic preservation, rooting is the only way to go.
in november i spoke to tom spereano about testing an aquaponics bed to root
some of our champion tree cuttings. tom reported 80 percent success rooting
a few hardwood cuttings in his gravel beds, and we want to further explore
the potential of his system.
beginning next month we will be visiting trees before their buds burst to
take this year's early cuttings. i am looking for a few aquaponics
experimenters who can commit to take a few of these cuttings to try rooting
in their hydro beds.
a second opportunity occurs in late sumer to take more cuttings from these
trees,but the best chance for success seems to be with early cuttings.
rooting is the first step in a new propagation system we're developing which
involves accelerator growing containers -- a patented system of slotted
containers that air-prune seedling and sapling roots. the slotted
containers prevent the coiling, circling and self-girdling of containerized
roots that weaken over half of nursery-grown trees. the accelerator
containers promote the growth of a thick mat of lateral roots instead of one
or two roots coiled up in the container. this also eliminates transplant shock.
a similar system called "soil blocks" is used by european vegetable farmers
to prepare transplant starts for field plantings.
cuttings that are successfully rooted are transplanted into individual cells
of a tray of accelerator containers. as the infant tree grows and fills the
cell with lateral roots, it is transplanted to a larger size container.
accelerator containers range all the way from 2 inch square cells, 4 inch
square cells, 1 gallon, 3 gallon, nine gallon up to 25 gallon containers. a
tree can be nursed for three or more years by transplanting into steadily
larger containers.
we are also testing the use of certain mineral powders, trace elements,
vitamins, and microbial inoculants in soil mixes to boost the vigor and
spark the immune system of our trees. we intend to grow the best trees in
the world using advanced but earth friendly technology.
here in new york, this week we are buying an aquarium to start a small scale
aquaponics system in our large enclosed porch. once we master the basics of
aintaining the system, we will try a 1000 gallon tank inour patio. we will
reserve one of our hydro besfor these tree propagation tests.
anyone else interested and able to try rooting a few tree cuttings in
controlled, conscientious experiments?

Hi Andrew.
What can you tell us about the barramundi/aquaponics system (Andrew)
mentioned in an earlier post? Something? Anything?
Ted.

I'm good for the most part, thanks for asking. I hope you're well too, =
same as the rest of the list. Now, regarding your question:
Well, no. In fact they have quite the opposite effect. You see, a sand =
beach is a complete system sometimes hundreds of miles long. There is a =
mecanichal fenomenon called littoral transport, wich is the displacement =
of sand by wind and littoral currents (local currents along side the =
beach). In a beach, due to wave action and littoral transport, sand is =
moved arround and the displaced sand is replaced by new sand "brought" =
from another place up the coast. If you stop the sand flow say with a =
house or a shore protection structure, you may avoid erosion in your =
"little neck of the beach", but the sand that you're retainig will not =
fill the place of the sand that is beeing eroted down the beach. In =
shore protection structures, this is a crutial issue in design (Lenght =
of the strucure should not exeed the littoral transport path). Plants =
are used to stop erosion because they don't stop all of the sand dune, =
but just enough to mantain the beach. Beach houses should be built =
either far enough from he dunes or in a "palaphitic" structure, so the =
sand can move under it instead of getting caught by the construction. =
Remember nature tends to mantain balance by constant destruction and =
creation (the circle of life applies to every thing, even inorganic =
things and physical fenomena). I'll give you an example. In the =
northern coast of Baja California (a system almost identical as in =
southern California) The coast is constituted by cliffs, rocky beaches =
and sand "pouches" or small portions of sandy beaches. If you want to =
create a private beach on a cliff zone and you build protection =
structures without bearing this concepts in mind, chances are down the =
coast somewhere, erosion will attack the cliff and eventually bring it =
down, possibly bringing down the cliff side house of your neighbour (of =
course this just a very colorfull example perhaps a bit exagerated =
allthough not impossible, but the reaction to the proposed situation is =
completely real).
The value of sand dunes as erosion control relies in the fact that they =
are dynamic structures, not rigid ones.
Best regards.
Alejandro

Sorry Adriana, I guess I'm just a little hard of thinking today.
You'll have to clarify your message for me.
Get it? Effluent? Clarify?

Brian G., and Jorg O., and others-
Ya'll were chatting about the NASA water treatment system that was reported
on the Mars PBS TV special some time ago.
The following info is not about the very same cell we saw on the TV
show---I could be mistaken about that----- but it is on a related topic.
Just down the road from me- down in Round Rock, Texas - there is a company
called Micro-Bac International. Through a Small Business Innovation
Research (SBIR) contract with NASA's Marshall Space Flight Center in
Huntsville, Alabama, they developed a water purification system for future
space missions- but they claim there are some down-to-Earth applications.
They developed what they call a "phototrophic cell" for water purification
systems, which uses light and phototrophic bacteria. They claim it does
not require aeration.
(Hmm...but probably a constant light source.....)
The cell has been used for several industrial applications since the SBIR
project's completion in September 1995. It is now marketed as a liquid
purification product, called Mega-BacTF. The cell was initially developed
for use aboard future space stations and inhabited off-Earth colonies on
the moon and beyond.
The product, they say, is an all natural, nonpathogenic, environmentally
friendly bacterial solution that does not require special clothing or
equipment for treatment.
They claim it represents a new concept in waste treatment, with significant
differences from and advantages over existing systems that require oxygen
(aerobic) and those that do not (anaerobic). Dr. Dennis R. Schneider is
Micro-Bac International's vice president for research and development. Tell
'em old Ted sent ya.
For more information, contact Bob Lessels at Marshall Space Flight Center
256/544-6539. FAX 256/544-3278. email robert.lessels@msfc.nasa.gov. If
you do contact them, tell I got the information from an article that
appeared in the March April 1998 issue of Innovation- another NASA
publication that I look at from time to time when I haunt the library-
Innovations is a much more pared down publication compared with NASA Tech
Briefs, which I subscribe to.
I guess you can find them at http://nctn.hq.nasa.gov
Ted.

Gordon, I sincerely hope it has been tested thoroughly and does not show the
side-effects the genetically engineered soybean has shown.
