... or maybe not such a bad idea after all...

I am not completely familiar with the organic farming rules, so please
correct me if I'm wrong.

I understand that mined fertilizers and salts are allowed in California for
organic. If this is true then copper sulfate would be available as a biocide
and root inhibiter, and many execellant fertilizers like K2NO3 are available.

Since SDI can potentially reduce weed pressure, it could serve as an
enhancement to the effort. Unfortunately, Geoflow hose treated with
triflurilin (Treflan generic) it would probably be disqualified ... but
clean water and a little copper sulphate might do the trick.

Does anyone else have insight into SDI and organic farming?

To: Mr. Warwick Rowell (and all)

In your permaculture experience, have you run across a tame cover crop that
might serve to replace herbacides on the berms of vineyards.

Above ground drip really makes the weed problem worse on vineyard berms,
making extra herbacides or special tillage necessary. Just the right kind of
covercrop that dominates the weeds, but gets along with grapevines would be a
major breakthrough.

We have just completed our second course titled "Vines Wines and
Permaculture", which is run by a colleague with nearly thirty years
experince as a vine grower and wine maker. Our goal is to encourage wine
making at a cottage and neighbourhood level. I will consult him, and get
back to you.

On organics and Drip:

The product we use most here ( around Perth in south west Western Australia
- mediterranean climate, like CA) is called "drip in".

It operates off mains pressure, and has 2 or 4 litre/hr labyrinths that
stop ants and clogging, and can be inserted into the tube at 40, 70, 100,
and 200 cm intervals.

It is brilliant for most of our applications, where mulching is used
extensively. I have places in my garden where the trickle is 30cms
under the surface and still functioning perfectly. With the water being
distributed into the humus, which is protected from the the sun and wind
by a top mulch, there is little need for additional supplements into the
line.

If I was to do this, I would look at building an organic mix, and then
filtering it carefully before putting it into the system. Liquid manures
and the like. First choice would be worm castings. a filtered diluted liquid
is probably the best way to use pigeon and chicken manure. Various plants
have been used for liquid manures and compost starters. Comfrey is one that
is often used alone.

What can one inject into a drip line and not violate organic farming rules?
CuSO4 is inorganic..does this count?
I think the organic farming community should realize what potential drip has
in conserving water and not write it off completely if they have to inject
just one acid or non-toxic chemical. It would be ironic if they totally
ignored the industry. Things can be worked out.

To Warwick and all other interested parties.
I have been trying to raise hops on a non cultivation regime.
Historically hops
have been intensively cultivated and irrigated by rill irrigation. I
have been
putting down drip tubing down 30-40 cm below the surface and then
spreading
straw or other organic matter on the surface to a depth of 7-10 cm.
The
idea behind this is to try to imitate the no-till residue cover that is
typical
of the Midwest no-till farming. It seems that after a couple years the
residue
level gets incorporated into the top 6 cm and an organic residue level
gets
going. I have been trying to figure out how to get the residue breakdown
started at a faster pace.
For the record hops are a perennial plant that has a very vigorous root
system
down to 4 M. Given the no-till regime the roots grow under the mulch and
feed
on the residue. This has cut our fertilizer cost substantially. We
live in
an area that only gets 20-25 cm of rain a year and most of that is in
the
winter. Thus the dirt below the mulch starts to dry out a lot by the end
of
summer and I think this Kind've stops the composting.
I would like to get a discussion going on this subject. I am the only
person
doing this in the industry and most people think I am crazy. But I have
had
some very good successes with some varieties of hops but each one
responds
alittle differently to the program.

Thanks

I'm planning on growing 10 acres of garlic with Streamline drip tape
according to CCOF (Ca.Certified Organic Farmers) guidelines, and I'm a
novice at using drip irrigation. The garlic is being planted in wide 28"
rows, intensively on four inch centers. Originally I was going to use
Rainbird sprinklers to irrigate but after analyzing pump costs I became
convinced that I could save money by using a drip system. I'm under the
assumption that I can also use things like fish emulsion, and seaweed
extract and other organic fertilizers approved by CCOF and injected into the
system (I have used them successfully through T-tape in a 1/2 acre home
garden). Does anyone have any experience with using these fertilizers and
how to administer them through drip systems?
I'm pumping directly out of a river and filtering with a 2" inlet and outlet
disk filter. My consultant who is a drip irrigation specialist working in
grapes, vegetable row crops, and apples, said that I could easily maintain
the system by monitoring the pressure on both sides of the filter and
cleaning it regularly. Do these systems absolutely require that you use
chemicals to clean and maintain them?
Most people on this list seem to think drip tape should be used subsurface.
My consultant told me that in vegetable farming there is too much root
intrusion for SDI and a surface installation was the way to go. He also said
that at the end of harvest the tape could be rolled up easily requiring for
less labor prior to tilling and disking. What are the limitations of SDI and
what would be the best installation for garlic grown this way?
TIA.

Does anyone have any experience with using these fertilizers and
how to administer them through drip systems?

Whilecompletely un-familiar with fertilizers like fish emulsion, I am
confident that mixing up various field strength concentrations with your
water into a jar and letting it sit would be revealing. If the mix stays
stable and clean a day or two, it is probably o.k. Especially if you intend
to run untreated water behind the treated water. If the material
precipitates or starts growing things, then caution is warranted.

Craig

You might try using natural zeolite to hold the water in place . It traps
molecular water and keep mosture uniform.

sorry to all but list adminstrator for putting this out to everyone.

Interesting discusion so far. A couple of points.

My concern with subsurface drip is the result ofan expectation that my
inputs would come primarilly in the form of top-dressing, and therefore
out of the range of subsurface irrigation.

As to what's OK for an organic farm, here in California we have a
certification program, so the question becomes one of what's allowed
by that standard, if the grower wishes to keep his "certified organic"
label. I don't know the chapter and verse there.

A question that is relevant to this list would be this:

What problems shold be expected with biologically-active ammendments in
a drip system. "Manure tea" comes to mind. I'm thinking of the possibility
of various organisms establishing themselves in the emitters, for example.

Another question:

Anyone care to comment on experiences with convoluted flow (is that the
right term?) emitters? Netafim is one brand naame.

Geoffrey Leach

Concerning your question of using Netafim emitters and their convuluted
flow path, I have been using them for 8 years and I have not had any
problems. Their pathway is very large and they are able to pass large
particle better than most emitters. They also are able to flush
themselves out by raising the pressure and the little flapper inside will
lift and let the stuff pass. If you plan on using large particle stuff I
would go to the larges GPH output posssible and this will help pass more
stuff.

Leslie

Here at UC Davis, there was a graduate student working with partially
treated sewage sludge (yeccch!) as a water supply to drip emitters. He
used several different emitters as well as several water
filtration/treatments to see what was required to prevent clogging of the
emitters by biological growth (algae). He concluded (this is heresay, of
course) that clogging could only be controlled by administration of
chlorine, either continuously or in 'shock' treatments. I beleive that
manure tea or fish emulsion would have similar problems with biological
activity and that some non-organic means would be necessary for control.
Algae would probably not be a problem in SDI since it needs light, but
I'm sure some other bugger would flourish in the organic soup and it
takes very little to clog the passageways of most emitters. Perhaps the
organisms can be controlled using acidification with some
organically-appropriate acid (??).

I have used microorganizams in drip along with micro nutirents all
organic according to CCOF in water line. I get lots of plug eminters but
its worth it becuase being organic I have to keep the soil alive so where
the water is the microorganizems are and the mico nutrient the celated
kind. On Wed, 7 Sep 1994, Geoffrey Leach wrote:

You have raised the very essense of the problem. What makes plants grow also
tends to make bacteria and other things grow.

I believe many of the amendments recommended for organic farming are in fact
intended to enhance the bacterial flora of the soil, and that the while the
direct nutritional benefits to the crop are minimal, the secondary benefits
of the bacteria they promote are very beneficial to the intended crop. This
might lead us to believe that these adjuvants are dangerous to use in a drip
system as they will encourage various biologicals inside the drip system.

Point: not all bacteria will clog emitters ... only the one that form slime
or cohesive colonies.

Next point: most life forms are concentration sensitive to poisons. For
example, yeast in fermenting wine begins to die at between 11% and 12%
alcohol. If adequet nutrients are present, simply adding water will dilute
the poison and allow the yeast to resume multiplying.

Conclusion: If a biological adjuvant is added to a drip system with an
adequet concentration of an appropriate and acceptable biocide, then the
biologicals will not flourish in the distribution system ... and yet the
benefits of the adjuvant will still be realized upon subsequent dilution or
breakdown of the biocide in the soil.

Soapbox comments: I don't mean to sound stuffy using the term 'biologicals',
but we must remain open as to what we are talking about. When I first had a
biologically related clogging problem (as contrasted with mineral), everybody
wanted to call it algae ... it turned out to be slime forming bacteria.
Subsequent experience and reading has shown me that clogging can be caused
by minerals, algae, bacteria, fungi, plants, animals, or insects. The
corrective action(s) required is completely dependant upon the nature of the
problem.

Conclusion: If we discover the appropriate and acceptable biocides we can
distribute biologically active adjuvants through our surface or subsurface
drip systems at will. The non-organic farmer has all the tools available he
needs. The organic farmer must find out what tools are available.

>Another question:

>Anyone care to comment on experiences with convoluted flow (is >that the
>right term?) emitters?

I believe you are referring to turbulant path emitters, also known as
torturous path emitters. When fluids or gases are subjected to turbulance,
their resistance to flow increase expotentially ... as contrasted by a
non-turbulant orfice in which flow increase directly proportional to flow.
By creating lots of turbulance, the emitters tend to maintain a relatively
constant flow over a wide range of water pressure ... permitting greater
acceptable pressure loss due to long and small water pipes/hoses. This type
of emitter is contrasted with a pressure compensating emitter which requires
a moving or elastic part to maintain a constant flow over varying pressures.

Not all original manufacturers were successful at creating turbulant path
emitters that also tolerated some contamination. The remaining players today
have conquered most of those problems ... these companies include drip-in,
toro/netafin, rain bird, and bowsmith (and others I'm sure).

I have tried drip-in (including geoflow who uses drip-in design but
impregnates triflurilen), hardie and rainbird. All regulate water to
specifications. The drip-in has proved to be more bulletproof to
complications like frost, minerals, and backflow ... my rain bug emmiters
tend to freeze and break. There is little chance you could feed an external
emitter through a ripper shank tube for subsurface either. I think the
hardie turbulant path emitters are more dependable than their pressure
compensatin emitters .... but maybe by now they have gotten rid of that
faulty assembly machine in their p.c. line. I am happy with our hardie
emitters for surface applications.

I also use microflapper self clogging emitters ;-) which distribute water
very evenly but are extremely suseptable to biological complications. The
microflappers are an external pressure compensating emitter ... not turbulant
path. Perfect water required.

Netafim has a very good rating for even distribution of water, but is still
proving its worth for subsurface applications. For that reason some netafim
dealers will suggest that subsurface drip technology is undependable. Sour
grapes I suppose.

Geoflow, which uses the drip-in emitter design (and factory), has proved
extremely reliable and in my opinion has set the standard to beat in
subsurface drip technology. For reasons I don't fully understand, their
emitter design has very little problems with reverse flow contamination, or
water contamination clogging. By impregnating their emitter with
triflurilin, root intrusion problems have been nearly eliminated.

If you have weed problems associated with your subsurface irrigation, there
is now a label for using Triflurilin (generic treflan) by the Gowan Company.
This treatment will have the secondary benefit of preventing root intrusion
into untreated emitters. Remember though, Gowan's Triflurilin is only
labeled for weed control ... not root intrusion. Remember that when you file
your use report.

Leaky hose/pourous hose/soaker hose/ or whatevertheycallit is fine for run
lengths of under a hundred feet in perfectly uniform soil. Of course water
delivery rate will vary over time, but what the heck. Don't believe the
salesman if he/she suggest a 90% distribution uniformity over a 600 foot run
... they're full of it (in my opinion). I had a saleman tell me that ...
but I don't think he knew what d.u. is.

I am not sure my answer is what Geoffrey was looking for, but it does
constitute a straight shot from my hip of my experiences and understandings.

Monday, I visited the hydroponic greenhouse operation of ADM in Decatur, IL.
They appear to be a leader in the practical application of this technology
for growing lettuce and cucumbers. They have 10 acres under glass. They raise
tiallpa (sp?) fish in the water and recycle the nutrient-filled waste water
back through the system.

We'll probably do a story (perhaps for American Vegetable Grower magazine or

Hi All, The fertilizer product called OXYGEN PLUS, sold at retail outlets
contains a peroxide as one of it's active ingredients. As far as I know
it is only sold as a retail type of product. When it first came on the
market I talked with the owner-developer who claimed to have a lot of
research data. He thought that the product would have benefits in the
Container Ornamental industry. If someone is interested in the PEROXIDE

We obtain most of our equipment from a local full service company called Lodi
Irrigation. Our community also has an excellent supplier called Quantum
Irrigation, as well as many independant contractors who can procure and
install components and systems. Most brands of drip system components are
available to us here.

Our local irrigation companies have had to learn drip very quickly and on a
big scale.

Lodi has many new priorities driving us toward advanced irrigation technics.
Real water shortages are just on the horizon, so water conservation is
important.

Even more important than water conservation is vineyard management. The Lodi
Woodbridge district growers have generally accepted top wine grape quality as
their primary goal. Water management is critical to producing _consistantly_
good quality wine grapes, and drip irrigation is the best way to gain the
control needed.

Not only does drip give us even water distribution on short notice, but we
have enjoyed being able to enter the fields with equipment when ever needed,
and not have to wait for ditches to dry out and be closed. That allows us
more time to see if a pest infestation will stabilize before needing
treatment. With furrow irrigation, if the pests are threatening, you better
treat before you ditch ... you won't get back in the field for a week or
more.

IMO, some grape varieties should not be attempted here without drip
irrigation. Chardonnay is one. To achieve good quality, a moderate to high
level of water deficet should be maintained as the grapes approach maturity.
Then, when the grapes are ready to pick, it helps to give them just a little
water to hold them until they can all be harvested. Furrow irrigated
chardonnay can pass through optimum and beyond in as little as three days
without the benefit of a little drip applied water. I have seen Chardonnay
held for a week and a half with drip ... but that's the best I would ever
expect to see.

So drip for us has meant water savings, crop control, and reduced pesticide
usage. We may not be organic farmers, but we are a lot less pesticide
intensive and a whole lot more in control of our vineyards than before drip.
Our success can be attributed to growers working cooperatively to discover
the best technics, and our suppliers finding and installing the equipment
that does what we need it to do.
Every year can be a vintage year ... and it is getting to be that way here.

I seem to get mostly messages saying "unsubscribe" and other useless
stuff. For now, at least, I'll unsubscribe, but where can I go to see the
entries?

Hi, I'm a member of Trickle-L, and it seems I'm getting mail that should
just go to the organizers of the confernece. I keep getting letters from
those who want to unsubscribe, and replies to letters I never saw. Just
thought you should know.
