Thank you Paula for forwarding the Preliminary announcement to this
AQUAPONICS list.
I wish to add that AQUAPONICS subscribers will find this Conference
especially interesting as there will probably be a theme/session on
"integrated aquaculture systems". I like to invite potential authors to
consider presenting papers on the material flow of the aquaponic system(s)
that you may be operating.
Quantification of material flows for substances/wastes/nutrients generated
very useful information for business feasibility studies and to make your
bio-systems more robust to changes as well as to make more money. The
conference (IC-MFA-IBS) will provide new ideas on alternative fish feed,
problem-solving in tracing sources of environmental problems, prediction of
effectiveness of pollution abatement measures for large scale aquaculture
farms, etc. .
The scope of the conference is currently being defined by a planning group.
I hope that someone (Paula ! ) from this list will volunteer to join the
planning group so that aquaponics and the interest of this group can be
well covered in the process of scope, themes and topics identification.
Future announcements, scientific programme and funds for authors and
participant groups will be made via the mailing list ET-W11. You can

Can anyone tell me how to make a natural home-made nitrogen-rich liquid
fertilizer? Is manure tea (ie. comfrey, grass clipping, or ? soaked water)
a nitrogen-rich liquid fertilizer? Our compost is carbon rich at the
moment. I would like to balance it with nitrogen, without buying seaweed
powders or bone meal. Mel Bartholomew's "Square Foot Gardening" book makes
a valiant start but lacks details.
Has anyone seen a good chart or list of root depths (in soil) of various
vegetables (ie. corn, wheat grass, tomatoes, okra, cucumbers, peppers,
etc.) because we have 12 inches of soil depth around the shallow
foundation of our home due to underground insulation extending out 4 feet
from edge of slab. I have been searching for this for some time without
success. Anna Carr's "Companion Planting for Gardeners" has a short
beginning, but not very comprehensive.
Any encouraging directions, advice, charts, lists, references would be
appreciated. Jorg ostrowski

Yes, you could try fish emulsion(fish in a blender) as well as a shovel
or 2 of manure in a trashcan of h2o.

Jorg,
I was under the impression that adding lots of grass clippings to your
compost pile would supply plenty of nitrogen. I don't know that it's
necessary to make a tea.

Based on most people who are growing in trays above ground, I would say
that 12 inches is adequate for just about any crop that you want to
grow.

Hi folks
A question about strawberry flowers and sporekillers like Desogerme or
Sporekill....is it possible that a sporekiller apllied as a spray can kill
flowers? Although the flower's petals and calyx doesn't die, the fruit part
of the flower does. It might be Botrites, although there are no rotten
fruit - typical of Botrites - coming out of the nursery. The idea with using
a sporekiller as a spray is to kill spores on infected plants and so prevent
healthy plants and fruit from being infected.
