Another Trailed/S. propelled debate

[Whynot]

I know it's been covered before, but looking for some help/advice.
We're currently running a 15 year old Bateman RB16 24m 3000L machine, which is fine for our 850acres of arable/Maize.
We have an oppirtunity to make our own fertiliser off our AD process, but unfortunately it will be rather weak. We will have 650-700m3 of a 10%N,10%S product which is roughly 1/3rd of the strength of normal N liquid ferts. It will be the equivalent of 180t of Nitram, but time consuming with current setup.
Any ideas? Currently thinking second hand 4/5000L self propelled or maybe back to trailed. What are the new trailed ones like? John Deere or Chafer?
Bowser?
Looking forward to some help as with current system I could be spending 30-40 days on this job alone!!

Apply it on tramlines with umbilical.

Had thought of dedicated tanker with24m booms.
Not sure it would be accurate enough. Was thinking driving a bit slower and maybe going to 36m. Is 600l/ha achievable?

Bio digester down the road puts digestate on their own fields with a 24m umbilical. It is very heavy especially when dragging pipe over large fields. They have 300hp+ on it and often another tractor in the field moving pipe. Lots of banks though.

I put separated slurry on wheat with a 7.5m trailing shoe. the problem you would have with a tanker and 24m dribble bar/tailing shoe is the weight and also the speed the tanker empties you will have to drive quickly to get to the end of the field, if you run out part way up a tramline when you come back with the next load to continue it makes a big mess quickly driving on previously spread ground. Most of my fields are about 20ac and we try to empty in 1 run up the field. Often we dont spread on the headlands as it just causes too much mess. If the ground conditions are right you can spread up to early stem extension without causing too much damage.

Having said all that we will probably go for a bigger tank and 12m next time. Mostly dry shallow chalk soil here.

We use a self propelled Holmer tanker(contractor) for spreading digestate. I'm looking for help in spreading the liquid fertiliser we are hoping to capture. I think this would need to be done with the precision of a conventional sprayer.

Think I'd be looking for a second sprayer and/or bowser. Stick to 24m, as suggested, wider booms will mean some tramlines see lots of unnecessary traffic - negates a lot of the benefit of going wider. @Bumble Bee

You need one of these

We apply 8%N 9%S usually 820l/ha but up to 1600l/ha with our sprayers. With bowser backup you'd have that lot done in 5 or 6 days.
I'm fairly sure Landquip could build a trailed version if you preferred.

Looks good. What width and capacity is your sprayer? Where do you get your 8%N9%S from?

 

[Bumble Bee]

24 meters / 4000l tank.

We get the ammonium sulphate from John Hatcher & Co.
