Hello Franz thanks for quick http://feedback.We are tracking infiltration depths with GPS moisture probes wirelessly connected to the matched Software package to track improvements. Using either the frequency drivenC2A0 Hydrosmart water systems or the ESP frequency driven water systemsWater Infiltration root zone depth is faster and deeper. On almonds we are seeing approx. 18" deeper penetration infiltration. We will be in Phoenix at the Irrigation show this week. If you are wondering where to get more info go to http://www.hydrosmart.com.auC2A0 Or http://www.customizedwatersystems.comWe own USA distribution support on these non flow restricted water systems. The systems creates scalar energy wetter water with hydrogen bonds broken. Wetter water soaks in the ground faster and breaks up scale into usable root nutrients in high TDS water. Units are all Green http://performance.We are dropping 3 more ESP... Read More

Subject: DIY irrigation Media Filter

Hello, I'm trying to build a media filter for an irrigation system, likely using two54 story, two 45 gallon drums and pvc piping. It uses sand and gravel, water is forced through the danged. I have a general schematic, bit not enough details. I know that a pressure relief, I mean air vent, is involved. Specifically, I am quivering what size air purged I will require. Any information helps. Thanks.

I don't even know my own system works. However, I will will say that if you are running 40 GPM through a filter that can only handle 9, your big problem is going to be volume not pressure. If the filter is only designed to handle 30 gpm of water flow, you are very quickly going to overwhelm its ability to filter the water.

You should be able to put a simple valve before the media filter to restrict the flow going in. It should not damage your pump, however, it's a waste of energy because the pump will run at the same speed it normally does.

The 9 GPM capacity of the filter will also cause you problems down the line, as I mentioned in one of my previous replies, unless your irrigation system is sized or controlled to only use that much water (or preferably less). You will lose pressure and the filtration will stop working.

My concern with anyone trying to DIY this is that even using

Subject: Food Safety Regional Lead for Tulare, Fresno, Madera, and Merced counties

Good Morning Ya'll,

My name is Jacob Roberson and I am the Food Safety Regional Lead for Tulare, Fresno, Madera, and Merced counties for a non-profit organization called Community Alliance with Family Farmers (new to Fresno area). CAFF is well established all over California except for the Central Valley which is where I am based out of (Fresno to be exact). I wanted to use this post as a source to contact farmers who are struggling with food safety and cannot afford to hire an outside consultant to come to their farm, perform assessments, help with documentation, and get their farm ready for a 3rd party audit. I perform the same duties as an outside consultant but my service is no cost to the farmer. CAFF is a non-profit organization looking to better food safety standards and procedures practiced on small farms / farms at a disadvantage (financial hardships, language barriers, new farmers, etc.).

Subject: Cold weather irrigation advice needed

I have questions about using irrigation systems in cold weather. I live in new England, where vegetable growers may like to be using an irrigation system in march, April, and may, where the night temperatures can often be below freezing. I'm trying to imagine how this can be done without damaging the system.
I use an above ground electric centrifugal pump that pushes 40GPM though 1.5" black poly tubing. The entire system is above ground, including a bulky 50 gallon media filter.
I am imagining that in order to use the system in spring, my ideal move would be to build a foundation for the pump, valves, and media filter.. So it would be underground. Then bury the lines as deep as practically and economically possible...12 - 18"using a single shank subsoiler and cheap trailing tube feeder attachment. I would also need to install valve boxes at every connection in the mainline, and every place there will be

thanks good information. I was talking about burying them

mainline hat deep, not the headers or dripline...anyway, its probably overkill. I like otour idea of just leaving the valve itself exposed...that could work... Typically I will have a few hours of warmer day temps to help thaw out frozen sections before I start pumping.

Subject: Quick Interview About Irrigation Systems

Hello All,
I am a Mechanical Engineering Student at the University at Buffalo in New York. I am working with a few other students on our senior design project, and our project is to create an irrigation system that will better conserve water. We're seeking information on current irrigation systems, as well as what consumers would like to see in future irrigation systems. Is there anyone I can do a quick phone or email interview with about the topic?

Here are the questions, please reply to any or all questions!

  1. What specific services does your organization provide?

  1. To you, what are the most important functions of an irrigation system?

  1. What are your biggest problems with current irrigation systems?

    1. What changes would you recommend?

  1. Do you find that certain crops or areas do not get enough water, while others get too much?

    1. What do you believe causes this?

    2. How do you try to regulate

Subject: Well pumps and sleeve liners

We are having some well and pump issues. I will start by saying my knowledge of wells is minimal. I want to turn on a pump and get water to my field. Over the past year I have learned much more than that but still have a long way to go. We have an old well shaft with a newer 200hp electric motor that is way too much for the draw that we require. I was hoping to have the shaft repaired/cleaned and a smaller 25hp submersible pump installed. I was told by a well company that they have a patented corrosive cleaner that will clean my sleeve and no brushing would be necessary. Does anyone have experience with this type of project and can offer advise? Thanks and I look forward to hearing from you all.

Subject: melon and watermelon irrigation

When is the best stage to back off/shut off water on melons and watermelons (Or does anyone just keep watering??)? We have fruit at a very wide range of stages, and we still have flowering as well. some watermelon are almost twenty lbs, while others are barely pollinated. Our honeydew are 4 weeks from our 'days to maturity' and the watermelon are 3 weeks out.

Thank you Paul and Helmut! That is very, very helpful. We will try preirrigating for planting next year (we preirrigated, but only a short set to make hand planting easier in cloddy soil). And I will take a break, then give more water next year. We gave 12 hours per week at the peak. Only 6 hours at the beginning and just recently. And I will take your advice and shut the water off in about a week, then regroup for he second crop. Thanks so much... It's very much appreciated!

Subject: Looking for tree crop growers interested in on-farm research

Hi all

There is much buzz about carbon farming, soil health and regenerative agriculture this year, and many farmers (and researchers) are interested in developing on-farm soil carbon and soil health monitoring.

I'm interested in finding someone interested in developing regenerative agricultural practices on their existing orchard (focusing on citrus, avocado or almond but open to others) in order to set up some medium term (2-5+ year) monitoring projects modelling soil-building practices. These might include compost application (as per the Marin Carbon Project: http://marincarbonproject.org); intensively managed/short-rotation grazing; intercropping, covercropping and alley cropping; alternative irrigation practices; or other methods depending on the goals of landowner and research potential of the site.

A bit about me: my background is in evolutionary ecology (BSc., MSc.), but I grew up farming and

This sounds like a very good starting point for a lot of contemporary 'aggies'. Some terms are new, but the sound of regenerative suggests a 'sustainable' tone to it. I would love to open up interest in worm castings as part of that process. I've been a small scale worm farmer for 18 years now and haven't seen enough commitment to the principles that Elaine Ingham has framed in her studies about soil health and fertility. If you have the desire to follow the health of the soil below the surface, please get in touch with me at PJ Dunn Working Red Worms in Galt, CA.

I'm sure that the process that occurs in the transformation of compost to castings involves carbon AND regeneration. We sell castings and worms and can provide education to get anyone started in turning their farm waste into mother nature's best and most well balanced fertilizer! Alternative is no longer a 'dirty' word, it is just

Subject: Need Help Choosing an Irrigation Pump

Hello,

I plan to source water from a nearby stream for irrigation. This stream is roughly 200' from the first location of a drip irrigation supply line. The next supply line is an additional 200' away. I plan to use valves and splitters to choose which area I will be irrigating, but I plan on only irrigating one zone at a time. The largest zone is roughly 3,600bedft, likely split up into 100' rows or so,..so picture 36 100' rows for this area. Judging by an estimation for elevation from bottom of stream to the high point in the field, I will require a pump which can push between 20 - 30 ft of head. The drip tape operates at 10psi, but I've heard it could also operate up to 30psi. I plan to use a quality pressure regulator with a gauge to control pressure supply to the drip system. I am a little worried about creating too much back pressure on the pump. The lines from the pump to the drip supply line will
