A big pile is hard to turn.
-
I haven't got a sprayer yet. Was going to get one this year but other projects took priority. If I got a sprayer, I'd likely start weed control with it...so just as well we didn't. Don't like to be around the herbicides really.
We are farming only cane. Quite frankly, looking to get rid of it all. I think farming in Isaan was a nice idea, but I don't like it much out here. I miss doing what I was doing before I did this to my life.- 1

How did you find that worked? Most people around here just throw it at the cane....seems like a waste to me if not applied well.
-
K. Thanks for that.

Anyone ever try this? For foliar feed or through drip system. I have a bunch of fertilizer that I would rather like to apply as liquid. I've been reading about it but am still unclear about whether it is possible to dissolve regular NPK granular. Any experience?

Get a big bucket! lol.
It should be in the neighborhood of about 200 litres a minute. I fill 1000 litres in about 5 minutes.- 1

Between Farangs...what happened to the idea of helping each other out? Waiting for the next guy to hook up so to take advantage....glad I'm not your neighbour.

Correctamundo....bit of a pisser really. First guy takes the hit full on. I'd hate to be in the position of asking Thais to help cover the cost. Especially after that fact. "Fat chance in hell" as my mother used to say.

Update,brought a 80amp stepup transformer which does the job to get it working
The thing I don't understand with the casing is we hit water at 23meters so I can't see the point in them going to 60meters if its not cased to at least 23meters,anyway we have good water now and the missus is happy and the kids have clean water for their pool.
Win all round in the end'might look at shoving some 4inch casing down it soon.
Isn't your pump 4"??
-
Power.
In the neighbourhood of 10,000 per pole. Everything included except the meter and hookup. 40 meter pole spacing. Assuming they do not need to add transformer(s). If so...more.That's what it cost us.

I know nothing about electrics. But it sounds like you need a bigger breaker. We run our submersible (2 hp) off of a 30 amp....off of a generator.
Casing the first 6 meters (if even that) is pretty standard here. They say that they case it down to the rock and after that, you don't need it. That's what they tell me and I don't know enough about drilling wells to know any different, but I suspect it is just another Thai shortcut. Having said that, we haven't really had many problems yet with the wells we drilled last year. None of them were finished properly IMO. The problems that we do have are with wells that didn't produce well from day one. They were done by poor quality machines and personnel.
None of my wells have a proper casing, or a downpipe to the bottom with a well screen or gravel packs. I'm not bragging, I'm just saying what they done for us and how it works.
BTW. If you ned to raise your submersible, it's not that big of a deal. Hopefully they removed they one way valve, that'll make it easier to raise. -
Molasses is sprayed on to combat nemetodes . Not suggesting that it is in this case here tho
What are nematodes?
It's ok. Just googled it. Google's great.

Guess my "edit time" is up.
Miscalculation. 5 drippers per metre, not 3.
!00,000 litres per hour. 1666 litres per minute. 416 gallons per minute. Yikes. Now am looking at 6" pipe and a pump that'll flow that much water.
Right??
No. It's 4 drippers per metre. No. It's 5....I'm going to bed. -
hmmm. ok
The drip line is "rated" at 2 litres per hour per "dripspot" they are spaced at 20 cm, so 3 per meter. That's 6 litres per hour per metre. A 10 km system is 10,000 metre @ 6 litres per hour per metre. That's 60,000 litres per hour, or 1000 litres per minute or roughly 250 gallons per minute.
What if I run 3" pipe? Will that flow that much water?Btw...apologies to OP for hijacking his thread. I could start my own thread, but it looked like he had solved his problems.

Quick Google check came up with the following, looks good and should go a long way to help you, at least in getting your thoughts together.
http://irrigation.wsu.edu/Content/Fact-Sheets/Sprinkler-and-Drip-Equipment.pdf
System layout is still important but this article doesn't address this subject.- I can possibly help you if required.
Ok. Thank you. Just a quick skim is making me sweat. I'll read it a little slower and see what sinks in to the old wood block.
Really, I have most of the system built already and there are many variables in finishing it to the size that I want. Some of these variables are within my control. That means that I can customise the system somewhat to fine tune it.
I am really more interested in the electric consumption of a 10 hp motor run at 50 % load capacity. Probably I should just google THAT and start there.
Thanks

Last note. I need to get 10 kms of drip line to run off of one pump for this to be worth doing. I suppose a handy tidbit of missing info is what pressure the drip line is supposed to be operated at. That is something that I don't know. Not yet. Global is a half day trip. My answer is there. I think.
-
Ok, I'll try.
Running 100 -300 meters of 2" plc. Then, off of that, I'll run about 10 kms of 5/8" drip line. The 2" pipe varies depending on which system I am sending water to. We'll run about 8 of these systems that will operate independently of each other but all connected to the same pump system.Each system for 2 days on a continuous cycle. The entire field will get water every eight days.
I'm not sure what pressure we are running at. We're not that advanced yet that we put a gauge on the systems What we do is open the appropriate number of valves for the supply that we are getting. When the system is pressurised and the drips are dripping well, that's how big our system is that day. So far what we are getting is about 3-5 kms of drip line off of one pump depending on how far we are having to pump the water to the system and which pump we are using.
We are using a few different configurations of pumps. A 2 hp submersible, a 3" surface pump on a well, a 2" surface pump on a well, and one or the other surface pumps pumping out of a pond (best scenario). The submersible works well too if we are not sending the water too far or uphill.
The pump that I am looking at is not that expensive. It's the most expensive that they have of this type. I'm not a fan of buying cheap and then re-buying later. It is not designed to pump out of a well. It will pump out of a pond. They say it will pump up to 1 bar for 1 km at 2" dia. They recommend a kubota but say that a 10 hp mitsubishi will work well as well. They call the pump a "pump reng dan" in Thai. It means pressure pump.
Any of this helpful? -
On the topic of pumps and stuff.
I've been running several kilometers of irrigation drip tape off of several different pumps, with some success. I want to expand my system(s) and pump out of a pond with a higher pressure pump. We are just getting electricity at this particular piece of property and in enquiring about pumps, motors and stuff at the local store, they figure that I'd need a 10 hp electric to run the pump that I want. They have both and I've bought a lot of gear off of them already, so I do trust them....to some extent. I trust that they won't knowingly steer me wrong or rip me off.
Can anyone tell me how much it'd cost me to run a 10 hp electric motor for 12 hours under load? Or could someone outline the equations to help me figure this out on my own?
Right now I am paying about 250-300 per day in diesel fuel (per machine) to run 10 hp Kubotas, and I'm running 3 machines, but only two systems. I think I can pump the same amount of drip line with one pressure pump as I do with 2 centrifugal pumps on the top of wells.
I'm going to test my theory first by running the large pump, on a large system off of a Kubota, but I wonder if 10 hp electric would be more efficient. I'm not that bright about these things.

Info. One year old prices
A 4" - 1 1/2 hp Mitsubishi submersible (2" out) will run you about 18,000 baht.
A 4" - 2 hp Mitsubishi submersible (2" out, 200 litres/min) will run you about 24,000 baht.
A 3 " - 1 hp Chinese submersible (1" out, 40 litres/min) will run you about 4500 baht.
Frankiln pumps will price in the same range as the Mitsubishi's - give or take a bit.
I don't know about jet pumps, but by the looks of the pic my guess is that price wise, it would compare to the Chinese 3" submersible....maybe a little more, but not much. Not sure of it's capacity but probably in the same range as well. (40 l/min) -
Sandy ground?? first-up a properly installed well shouldn't pass any sand after initially being developed and secondly, any sand in a jet pump is just as detrimental as in a down-the-hole bore pump. Sand is sand and abrasive to pumps especially in high velocity areas such as a "jet-pump" venturi which will suffer considerable erosion.

informative thread. thanks.

I figure it would be molasses. But the OP said that they filled up at the river. You don't get molasses at the river. We just put a couple of truckloads down on one of our fields. The stuff is not colorless, nor odorless but it is commonly used before ploughing or after cutting your cane crop down before it starts to grow again.

Did you ever figure out what it was?

Word of mouth is probably your best bet.
Warning: third party "helpers" often inflate the price and do their best to stay in the middle. Bypass them. Don't settle anything with anyone other than the seller. The seller then paays the introduction fee of 3% to the person who brought you in.Good luck.
PS. I totally understand your comment about the BS suggestions. A lot of "smart ass know it all's" on here who love to read what they wrote.

I understand that you know which dog it is from your opening post.
I'd demand satisfaction from the owner, either in cash for the birds, or a dead dog.
