liquid fert to horsch co3

Case140 · Nov 26, 2017

Thinking of fitting liquid fert to a co3. Thinking old sprayer tank on front linkage with electric pump to simple manifold(s) piped to legs (my gen openers already have LF pipes). What Im wondering is what Type and amount of fert are you guys using so i can work out pump size for my 3 m drill? Normally dd between 8 and 12 km/hr. Particularly for spring crops.
Anybody using a diy electric pump and where did you source it? Is it variable speed or how do you control rate? Interested in simple systems which i can build myself, thoughts or advice welcome please!

@SimonD what output do you get from your electric pump?

Anywhere between 100-150ltrs/ha. I used a 12v window cleaner motor variable switch to control motor speed.

Thanks, what type of pump do you use? Would a demand type (similar to an atv sprayer) work do you think?

So at say 10k, 3 m drill = approx 3 ha/hr. so 150x3=450l/hr =7.5 l per min. So would something like this do?

plus maybe this:

Or am i thinking waaaaay to simple??

I ordered this from the U.S via eBay.

Are you using l fert already or are you setting up?

I've been using it for 2 years. I fitted it to de-risk WOSR and happy with the system vs cost.

Case140 · Nov 26, 2017

so is your system a tank, filter, that 12 v pump, relief valve, to a manifold just piped to the legs? what drill and width are u using? Do you vary the motor speed with the wiper switch to vary rate? Is that hard on the motor and does it give trouble? And what fert are u using? Sorry for all the questions but decided to put all in one post!

Yes, but with no relief vv. Neil Challis from Challis/Reed supplied the manifold and is happy to make them. He's on Twitter and very approach.

From the manifold it goes down to each tube in 8mm sprayer pipe, at the end I've cut 1" 6mm pipe and inserted it into the end, this gives me a restriction so evens up the flow. Cheap eBay connectors and fert delivery tubes that I made myself. Clive may be supplying tubes for CO drills which would make it easier.

Neil also supplied a rocker type switch which is activated by the land wheel, all pretty basic but it works well enough. If I had more justification I'd look at what Tim Parton or David White have done.

Fert has been standard Yara but looking at AS.

Thanks a million for all your help. lovely looking job by the way!

Fitted nozzle bodies to the manifold and put restrictor plates from tee jet in to get required flow 10 mm tail for pipe got supplier to work out the size of plate works well

Thanks mill!

Have you tried or had an original Horsch fert pump @Case140? Maybe an ibc fitted on the front of the tractor? I knew someone who ran that system very successfully..........he is on here somewhere?

Case140 · Dec 2, 2017

Thanks. I did make a phone call to my horsch dealer re a pump.....am still recovering from the shock!
Have pretty well nailed down what i am going to do except .... What diameter stainless pipe do I use on bottom of coulter?
Looking at all the pix here they look about 4 to 6 mm inside dia? Any advice appreciated

Case140 · Dec 3, 2017

Sorry @SimonD Reread post and you did say 6mm at the end. My eyesight is getting worse!! Thanks

i dont belief it · Dec 3, 2017

Using 6mm inside diameter here only reason being that the rubber pipe fits well onto it

Case140 · Dec 3, 2017

Not to regulate flow? I thought you would need a restriction close to end of pipe or else the longer pipes would not fill at the same time and uneven rates? Are you using similar size pump to @SimonD? I think I am overthinking this!

hollister · Dec 3, 2017

Does the system pictured have a manifold then the pipes split ok in to two pipes down to coulters?
