750a fert system

All very neat and tidy. What is on the coulter end of the fertiliser delivery tube?
it's really hard to get a pic !(I tried) basically the stainless tube has a small nozzle in the end of it that squirts the fert onto the back of the seed tab - its held in position by a tube welded to the back of the coulter that has a grub screw tapped into it to pinch the fert tube
the tank can be removed very easy to go on a 3 pt linkage( if required) so maybe if we want to spread weight more evenly in wet conditions we might put it on the front of the tractor. It can also be used with other machines / drills in the future and we have fitted this so the 750a can be easily returned to standard should we sell it in the future

Looks a good job. Will the fert sit with the seed or will it be separated from it like the CS?
And probably been asked many times before but is this for P & K liquids mainly?
Have you fitted a blockage sensor system to it? Thinking with it being so close to the coulter soil might flick up into it then the liquid backs up and blows the pipe off the distribution head?

no fert / seed separation. I agonised over this for a while and after talking to a lot of guys already doing this it seems unless your wanting to place large amounts of N there is no issue with it being together
blockage wise that's covered by the controller, the pipes run in the shadow of the coulter though so I would think unlikely to block, the pipes all have non return valves in them so it cant back pressurise
can't see any point in K placement plants don't need K until stem extension ???? I plan to try P in the for of liquid MAP / AS mix, straight AS, UAS and some polyphosphate - all at pretty low rates, will try throwing some molasses in with the above as trail also

Very nice Clive.
I'm drilling some spring barley with dry dap down the spout today(the main reason is I just fancied trying it again to see it looks nicer as a pop up, I know a yarn on plenty about being unconvinced but I thought I better try it again).
Only doing a rate of 35kg/acre though which is only 12 units of N and 30 units of P, which is probably too little N to demonstrate anything. Will change some cogs tomorrow and up the rate in another field to see as a compare/contrast.

Looks really good and definitely fitted in well behind the seed tank, what controller are you running and obviously you have a hyd pump is it on the fan spool or it's own? Are you using a Ramsay air unit and then taking air off the tractor. Sorry for all the questions but just looking at it is making me think of a few ideas.

I'm not sure 35kg/ha is going to make much difference. We put 166kg/ha in and did see some difference initially. Can't really see much difference now versus broadcast.

No it won't, it was 35kg/acre though not ha. I'll change the cogs for the next few fields and see if say 150 kg/ha compared to 75-80kg/ha makes a difference. It was just to see if it makes if pop up a bit earlier or gives it something as I'll hardly put any fert on proper until I can see the rows.
Its just for fun really, see what goes well etc.

Ah yes, misread the unit.

Nice work - look really good!
This will be great for spring barley and OSR and raise your yields!
Its a RDS 34i with GPS controller, went through the idea of running it through the x30 to reduce in cab boxes but it seemed to just over complicated and add unnecessary expense.
No air from tractor its a flow based rate and its on its own spool from the tractor
lets hope so !

100 l/ha product is the max I feel is practical
going to try a few products at different rates and try and learn what works best
UAS , map / urea mix, straight AS and straight urea all on my list to try and I have all these available anyway, would also like to try so e polyphosphate if I can buy a small qty economically to try.
So not a massive amount of N really and any N placed will be removed from the planned top dressing so no additional cost just a early seed bed % to make up a bit for lack of mineralisation via tillage is the idea
Jurry on placed P is still out for me but will still try a bit for comparison (I have a spare 1t of map kicking about !)
I'm even going to try a plot with no fert and just molasses ........ You never know !
Experiment and learn what does and does not work for me on my soils and crops basically !

S&K system by any chance?
Yes it's their "nitro bar' front tank
