Date: Tue, 30 Sep 1997 08:30:17 -0700 From: Richard Mead (rmead@AGRILINK-INT.COM) Subject: Re: Aeration/SDI on turf Dear Wally and others interested in drip and turf, There was a 1995 Sunset magazine article on buried drip irrigation in turf. I was scanning the Net this morning after reading your query on aeration and decided to see if Sunset put their articles online. Sure enough, the article is there at: http://pathfinder.com/@@86sGYQQAjBhB8kT8/vg/Magazine-Rack/Sunset/1995/June/d ripirrigation.html I'm not sure if it has sufficient information regarding aeration for you, but it's a start. There's also a CIT online paper entitled "Subsurface Drip Irrigation (SDI) on Turfgrass: A University Experience" at: http://www.atinet.org/cati/cit/rese/95/950104/index.html Contact Dave Zoldoske (david_zoldoske@csufresno.edu), the director of CIT to find out more on aeration, turf and SDI. The Microirrigation Forum* also has some archived discussions regarding turf and drip issues: -SDI on golf greens/athletic fields at http://www.mif.org/sdigolf_fields.html -SDI in Turf at http://www.mif.org/turf.html -Drip and subaeration system at http://www.mif.org/aera.html Finally, I believe Trickle-L subscriber Dave Enyeart of GroAire Irrigation has done some remarkable work with aeration, yet I don't know if he has experience with turf.

Date: Thu, 2 Oct 1997 14:20:53 -0700 From: ClemWehner (cww@PACIFICCOAST.NET) Subject: Moisture Sensors, Comparisons Back in 1992 I was hired to do a market survey for a Moisture Measuring system then being developed, based on earlier knowlege that used Time Domain Reflectometry (TDR). The survey looked at several applications linked to Agriculture and Industry. Of particular interest were Irrigated lands: 1) the cost of water and moving it during growing seasons, and 2) post-harvest measurement and management of moisture in large volumes of product such as grains and dried fruits. Insofar as Irrigated Land, the section, "Present Methods Available to Determine Moisture in Soils" can be obtained as an excerpt from the Market Survey for TDR Moisture Measuring Instruments. This review would be useful to current Trickle-L and Irrigation-L discussions of Soil Moisture Sensor Comparison Papers. There's need for an update, though: After I did the 1992 TDR survey there have appeared in the marketplace at least two other Soil Moisture Sensor methods: 1) Multisensor Capacitance Probes 2) Heat Dissipation Blocks. Meanwhile, the TDR moisture-measuring concept is now commercially available as the "Moisture Point" system, manufactured and marketed by Environmental Sensors Inc., Victoria, BC, Canada 100-4243 Glanford Avenue Victoria, BC V8Z 4B9 Phone: 250-479-6588 Fax: 250-479-1412 E-mail: admin@esica.com Yours truly, Clem Wehner C.

Date: Thu, 2 Oct 1997 22:22:21 -0400 From: GroAire@AOL.COM Subject: Re: Aeration Hello Wally, I have 15 years of experience of using subsurface drip to deliver my air management programs to the root zones of all crops including bluegrass and native grasses. I installed my first subaeration system prior to drip tapes twenty years ago and eventually moved into tapes as a more efficicent means of delivery. My oldest bluegrass system is was installed 13 years ago and just finished it's 14th season. The most recent site installed was in Nevada by an extension specialist who is elated. One of the most striking benefits aside from bacterial stimulation is reduced root intrusion. Other benefits follow: 1. reduced incidence of fungi and anaerobic disease. 2. no longer requirements of core aeration 3. better penetration of water into the soil profile 4. faster breakdown of organic matter 5. increased worm populations And too many more to discuss in this short dialoge.

I am now prepared to move to the next level even though the present market is just now developing. Nothing like staying ahead of the game by 20 years. I would like to pose a question to any interested parties - particularly in California ( as there are some entities who would be interested in cost sharing in some beta plots).

The difference is the degree to which it is considered to benefit humanity or incorporate new technologies which would benefit mankind even if unproven. It requires a standby letter of credit drawn on one of the top 100 banks. In energy savings technology, generally we can guarantee minimum 35% savings annually guaranteed by insurance company and the loan is repaid out of savings. In those cases, The terms of the standby letter of credit will contain language that it will never be drawn upon. ------------------------------

We seem to have a plague of small moles that creep just under the surface of the soil, lifting it up slightly and leaving their tunnels behind. Within days the irrigated beds are full of these tunnels with the result that roots dry out and water transfer and distribution through the soil is chaotic, be it under micro or drip. We have tried flooding them out, but ran out of time and water, pouring pungent smelling liquids into the tunnels, placing mothballs, commercial mole repellent in them, planting garlic or onion --Ha! Ha! they just go round these bulbs. Also read somewhere that their burrows are metres underground. Any solution someone?

Date: Sun, 5 Oct 1997 13:59:26 -0400 From: Frank H (suemc@GATE.NET) Subject: Re: [IR-L] Project Funding The range of projects is quit broad but they must have a humanitarian purpose. For example, developing a coal mine in an area of high unemployment would not be approved even though it provides work and income because of the adverse effect on the atmosphere. However implementing technology and application of research to reduce problems in existing mines might not only be approved but could be granted. We are working on a 12 mill project now that involves converting a large area of abandoned grove to organic and putting in a new irrigation system.Included is 4 million for application of new technology and research to demonstrate ionisation, colloidal chemistry and surface charge effects and electrochemical catylization. The governmant of the country involved will put a a 14 million letter of credit for four years which will contain language that it cannot be drawn upon. Other than the cost of issuing the L/c, the project will be done at no cost and almost no strings attached after loan approval. Depending on the project, the terms can be interest rate from 5% to 0%; partail grant and forgivness or total grant and forgiveness. Projects as small as 1.5 million can be done. The larger the project, the easier it is to do. Submit me a brief outline of a project (two pages) and I can generally tell how to change it to get it approved. Approvals and funding are quite rapid. We generally can move faster than the parties that are the recipients as it takes a long time for them to understand and check with the attorneys, etc. Disbelief is the first reaction. This is closely held information and only the top 100 banks in the world can particpate in this funding. The L/c must be drawn on one of those banks. Breifly it works like this. The recieving bank can draw 80% funds availabilty against the L/C as an "off the books" transaction. (not affecting their capital or uncommitted loan reserves). They take these funds and buy US Treasuries in round lots at of a minimum of $1 million. Bonds in round lots trade at a substantial discount to the same bond in $10,000 or $100,000 increments. By buying in large amounts (1 million or more) and simultaneously breaking them down and selling them in small amounts, they can make net 15% after all costs. Repeat this enough and the loan is covered. This is monitored by the Fed but more as to meeting the intentions of the program and not letting it get out of hand than to any details. Hope this helps. Frank hartman PS among other things, I have a Masters in Finance and I don't understand all of the Machinations of this program.But I don't need to. All I want to know is enough to get approval. This is still a fairly new program and how long it will be available isn't known. Ted Knutson wrote: ) Funding for what.

My company, WorldWater Corporation, is a solar energy company that speicializes in solar water pumping. We have technology that enables the use of solar energy to drive off-the-shelf AC pumps. This makes it possible to go deeper and pump higher volumes than traditional solar technologies -- making solar irrigation practical for many applications. The irrigation systems we have done to date have been flood systems, but we are interested in pursuing drip and other efficient methods. I would be interested in hearing from you about speicific opportunities to use our technology, or funding programs we could tap into for further R&D (relating to drip technology?), commercialization, demonstration projects, project funding, etc. Any thoughts would be appreciated.

For attaching the drip tubing to the polyethylene pipe that connects to the submains we used 8" stainless steel wireties since they were easily obtained, fairly inexpensive, and fairly easy to use. More recently someone raised questions about their longevity buried 15" below the soil surface. We expect this installation to last 10 to 15 years. Soils are the acid soils of southeast Virginia. Does anyone have any suggestions or ideas about this. We plan to expand this system and would welcome any suggestions. Norris L.

We have a virtual research program done online with people that come from a spiritual basis (Not a religious basis) and are working as a group to develop and implement new tools for healing in all areas. (the planet. mental and physical) It is called the Personal Healing Center. We have a financing tie and a vitrual corporation of companies and experts in many areas that are called upon for various projects. I am only the spokesman for they water end of it. All our work has been tested but it is done anonymously as no member publishes anything under their own name in any journal. This gets us out of the ego thing and in many cases the members work would either be at cross purposes to the company or institution they are working for or their work wouldn't be published in peer -reviewed from jealously or because it doesn't fit the model of the world of the reviewers. We are focused on the practical applications. Will it work ? If it does we spend time on it, If not, we go on to something else.

Date: Mon, 6 Oct 1997 21:38:42 -0400 From: GroAire@AOL.COM Subject: Re: Aeration in potato hills Hello Clint, I have been designing aeration systems for 15 years using drip tapes. A large share of the third party documentation has come from Universities and growers of potatoes. All tuber crops, potatoes included, respond exceptionally to aeration. Not only due gross yields come up, but the quality and quantity of number ones increases dramatically. We broke all records for Bonneville county in Idaho in one of the plots. At another test in the production of minitubers (micropropagation) at the University of Nebraska in conjunction with the Nebraska potato certification association we cut production time by 40% and increased total yield from 3 tubers per plant to 9 tubers per plant for the Norgold M variety. I don't believe I mentioned both plots received absolutely no commercial fertilizer or trace elements. I have also seen yields exceed the capacity of the harvester. I'm sure all this sounds too good to be true, but I've seen it replicated so many times I begin to sound redundant. All I can tell you is to try it. Incidently I design aeration and irrigation systems and currently operate in 13 states. If I can be of any assistance through education, design, or sales; please let me know.

You have a surface charge or zeta potential problem. Algae formation in pipes or ponds or rivers or filters results from the reduction of surface charge on particles in suspension. The same thing applies to river and pier sedimentation and silting. If zp were understood, maintenance dredging would disappear. In sand filters, the sharp points on the surface build up a net positive charge. Edwards and Monke- Ag engineering profs at the University of Nebraska and Perdue wrote a paper "Electrokinetic studies of Sand Filtration" in Oct 1967. ZP at the top layer 3/16 inch was +850 mv. Guaranteed recipe for coagulation and flocculation. The rest of the filter was -36 to -133mv. depending on particle size. (Smaller particles carry a higher electronegative charge.) which is why when you scrape the algae off the top of the filter, it will do an excellent job. Depending on pond size, etc., there are several simple solutions. Send me an idea of the size, source of water and method of entry and any outflow and any known chemistry. With gpm , pipe size and longest run, there is enough information to not only clear up the algae problem but also increase hardiness and growth of the plants. edmartin@AG.ARIZONA.EDU wrote: ) At one of our farms here in Central Arizona, we are raising tilapia in in an ) irrigation pond.

Controllers exist that have more immunity to the effects of surges than others. It is costly to create a system that can take a direct hit. Prudent grounding techniques, surge suppression and wiring will solve most problems. Can you tell me more about your particular cases?

A fully automatic self cleaning screen filter will do the job just fine!. To size the screen element of the filter correctly you will need to find out the smallest aperture of the nozzles or spray, divide this figure by about 5 to give the size you need. e.g. If your sprayer/mini sprinkler smallest nozzle is say 1.2 mm /5 = 240 micron. Closest standard screen size to this is 200 micron = 80 mesh. Note that a lot of the algae will go through the nozzle of the micro spray/sprinkler. The filter will take out the problem material. If the algae is real bad you could put back-up filters 80 mesh at each field valve. Other comments to reduce the nitrogen level in the dam thereby reducing the algae occurance would also be helpful.

While there has been good published scientific work demonstrating the increase in growth when CO2 is put into the irrigation water, I have been unable to find anything published that demonstrates the value of putting air either into the irrigation water or into the soil. This is important, because if indeed there was soil remediation and an increase in the aerobic bacteria in the soil then this would have a valuable application when disposing of sewage effluent into heavy soils. This is a major problem world-wide. If anyone knows of anything published or contacts with scientists working on this problem, please post the informnation on Trickle-l.

Date: Wed, 15 Oct 1997 08:59:26 -0500 From: "W. Bryan Smith" (wsmth@CLEMSON.EDU) Subject: Re: Algae ) )In my irrigation resivoirs I use copper sulfate crystals to control algae. I ) )don't know if levels to stop a;gae growth would be detrimental to ) )fish. Use of copper sulfate to control algae in fish ponds is a common practice here is the southeast U.S. Determination of how much copper sulfate to use depends on water pH and the actual volume of water in the pond to be treated. The Extension Service has been recommending this for years with no detrimental effect to fish. You can kill the fish by applying too much copper sulfate, and you can have little or no impact on the algae by applying too little copper sulfate. Dont' guess the pond's depth and size - measure it! A few notes on use from our Pesticide handbook: - Lower rates are required in low pH waters, higher rates are required in high pH waters. - Before using, test the total alkalinity of the pond. If the total alkalinity is less than 50 ppm, copper treatments are not recommended due to the high risk of killing fish (copper toxicity). - Under heavy infestations, treat only 1/2 to 1/3 of the pond at once to prevent fish suffocation (due to decomposing algae, I would assume) Check with your local aquaculture specialist on recommended rates and times of application for your area of the world. Maybe a harder question is will the copper sulfate affect my crop? I have no idea if it would or not - I'd guess that the amount would be so dilute as to be unnoticeable to the plants, but that's only speculation on my part.

Our early studies of drip on potatoes were not as favorable as had been hoped, but we can now carefully control drip irrigation. Consequently, I am considering reexamining drip irrigation for potato production in the Treasure Valley of eastern Oregon and southwestern Idaho. Your experience and publications would be appreciated. Since potatoes can respond to oxygen, I would like to incorporate aeration into our studied. Consequently your reprints or literature citations on this topic would be appreciated. Since the topic may be of narrow interest, some of you may wish to respond back to me directly. The silt loam soils typical of this region can set up pretty hard with higher soil bulk density after being saturated, soil conditions that are unfavorable for potatoes.

There is not one common solution for all installations. Please elaborate on your site or sites. If you just want some name of a company that makes this type of equipment, try Polyphaser Corporation in Minden NV. (702) 782 2511. Their products are the best protection for lightning I know of.

Date: Wed, 15 Oct 1997 08:36:59 -0400 From: Frank H (suemc@GATE.NET) Subject: Re: Algae/Aeration Clem\ Look for a supplier of swimming pool ionisation with a copper rod. This will put the copper into colloidal form. Crystals can have many undesirable side effects longer term. In colloid form, that doesn't occur. I have so far put fish in colloidal solutions at ten times the toxic level of arsenic, copper, lead,iodine, cadmium and silver. At the same level in ppm in non colloidal form, death occured within 7 days. In colloidal form, no evidence of toxicity and they they seemed to thrive. Copper /silver is a better combination of rods and you will see major changes in growth and vitality if the unit is the right size. the algae will disappear. when you first start using it, depending on size of pond, etc. , turn it on for about 3 hours/day and increase the lenght of time while watching the algae. You can contol the speed of the algae diappearance. Fast kills of a pond full of algae can result in outgassing as the algae deteriorates. It will pass but a little prudence will avoid it. Avoid aluminum or any divalent or trivalent cation. ps did I reply your earlier question on funding ? Upgraded to a new version of netscape and seem to have lost some messages in the upgrade.
