Dear Bert, Congratulations on receiving a SARE grant. We received one also
on greenwater tank culture. We will be building three 50,000-gallon tanks,
two of which will be located on vegetable farms. The effluent will be used
to irrigate and fertilize crops and improve soil structure. We'll keep the
group informed of our progress. We grew zinnia in our raft system with
great results, a large number of multicolored flowers. As the plants aged,
mildew developed. This occurred after the bulk of the harvest and the plant
were senescing. I found that the vase life of the zinnia was very short,
about 3 days. I will be interested in your results. There may be ways to
extend vase life, and maybe your flowers, grown in a cooler climate, will
have a longer vase life. Right now we are growing a few marigolds. They
always do well in our systems. Good luck. Jim R.

Jim,
The North Florida Research and Education Center is doing research on
hydroponic zinnias. I don't think they've published their results, but
when I visited last fall they had some definite conclusions on
recommended varieties, culture, etc.
If you haven't been there you should try to go on one of your visits to
Florida. They have a nice demonstration set-up.

There are regional programs. Go to CSREES. From the main directory you
should be able to find info on SARE program

Dear Elisheva Ruth et al.,
I am interested in such studies on earthworms, as I will be working with
orgs for agricultural systems and wastewater treatment. Any advice you can
give to begin such a study and research would be greatly appreciated.
Sincerely,

Actually worms have been used all the way up to commercial
and municipal levels to take unacceptable sludge or waste to
"Class A" ratings which is quite good. It is not a new thing
and gobs of studies have been done.

Great to hear of funding support in this area.
Since we are on the subject, I am pleased to announce that
www.idrc.ca awarded funding for my doctoral field research
in wastewater /greywater aquaculture and irrigation of food crops
in the West Bank and Israel. I am looking specifically at
low-cost biofiltration systems for ww/greywater; with and without a
vermicompost-enriched layer. I suspect that the diverse robust microbial
communities will increase metabolism of SS and N, etc.
Dr. Rakocy, it would be very helpful to learn more about your project.
Are you supplementing the fishwater with additional fertilizers?
What are the effects of soil structure, etc.
What are you measuring?
Do you have contacts in Israel?
Thanks for taking the time to respond.
Eli

No, all we add is calcium hydroxide to neutralize acid buildup.

We have taken before and after soil samples, but I am not sure about the
parameters. The horticulturist and agronomist have done this part. I will
have to get back to you later on this.

We measure inorganic nitrogen, organic nitrogen, total nitrogen, total
phosphorus and potassium added in aquaculture effluent. And of course we
measure plant growth response.

Thank you very much, I am less than 30 minutes from the florist that we will
be test marketing and I hope makes a difference. They do not want me to cool
