Examples of liquid fert programme.

[spikeislander]

Definitely moving towards liquid on our home farm before hopefully rolling it out across other agreeable customers, but interested in people's approach regarding analysis , splits and total n and s.
I'm looking at going 35n 7 s across the board to keep it simple but looks kind I'll need to do the small areas of osr with double top solid to be able to get the amount of sulphur on first dressing .
Possibly 32n 9.4s works better just curious about others programmes.
Thanks

Was always on 35+7S but moved onto 19+19S last year as acreage was halved so had the time, wasn't fun putting 70units on in 1 dose with 2500L sprayer. The sulphur definetly made a difference, may be worth doing the 19-19 at your quietest point of the spraying season and where a bowser could follow you and then back on 35+7S when you need to get through the workloads quicker!

Keep it simple ! We use one product throughout which is a home brewed UAS solution. I don't really want to use AN on my soil and I want to apply S every time we apply N as it's easy leached

Wheats get x3 applications of 300L/ha which gets 180kgs N on plus 100Kgs So3

OSR gets x3 applications of 350kgs /ha which gets 210kgs N on plus 115/kgs So3

Same product gets used in spring oats, libseed etc in seedbed and top dressed balance

We used to use stronger solutions but find this works better for us and lower scorch risk

Will certainly watch your experiences with interest ,,,,,, have often thought about going down the liquid scorch route but we do get on so well with our solid fert system ,,,,,, happy to stay at 24 m tho with no wish to go wider tramlines

 

[spikeislander]

Bit harsh to call it the liquid scorch route! Give us a chance?

IMHO you will never regret going liquid and will wish you had done it years ago!

 

[Mr Charisma]

I've always called it that . Every one I've ever known has always said 'we never scorch with liquid fert'

20 secs later they then come back with ' a bit of scorch makes no difference anyway , and by the time the next leaf grows past the scorched bit you can't see it '

I realise that liquid fert has a lot going for it , hells bells there's enuff folk doing it so there must be something right in it

How does liquid 'fert' stack up in pounds / acre ???

 

[spikeislander]

Not sure yet it's the logistics and accuracy that appeal to me. Maybe you have to expect some scorch but I've quizzed numerous people on it and I would say all have said they wouldn't go back. Got to be worth a whirl

Best way to reduce scorch is at night and finish by 7-8am. Rain is hit and miss.

I wouldn't use prilled if it was up to me and the sprayer had a sizeable tank and you had a bowser! Doing 6-7ha per fill and then driving 5mile back each time gets tedious very quickly! Accuracy is spot on, the KV Geo would be the only spinner I would get if staying on solids. I had a KV geo and a small capacity sprayer on liquid so could switch between them depending on price of fert. Didn't have a bowser and small sprayer so did more solid once the geo arrived.

3x lots of 32/9 here, split depends on season but +/- 250lt/ha each time = about 750lt ha total cheers dh

4 doses 26/5 @ 150 Ltrs /ha , also use high S granular product to get enough S on OSR and cereals 2nd year on liquid now so much easier not having to chase someone else around to get spreading done less ruts using sprayer ,more accurate etc etc

 

[spikeislander]

it sounds like 3 even splits is a common approach I understand this is easier but Im surprised the rates are not varied slightly in accordance to growth stages and demand from the plants etc?

This year we used 35 7 split in 4 starting 15TH march and the last split went on
12TH MAY
220lt 220lt 145lt 155lt

 

[dirty harry]

All depends on season & crop, could be 200/300/250 or 250x3, or 3x200 if less potential? This yr on osr been 2x 325, on wheat 200/300/200, as trimmed everything back (rightly or wrongly)? Just tailor it to suit really & ideally when overcast- raining - Dewey & not over 20 degrees = less scorch, - this year was a head scratcher & I did slightly scorch a few fields but it was dry /windy & it's fine now! - but to be fair even Moddus scorched!! Cheers dh

 

[Longneck]

I do 3 splits on wheat with more conventional rates i.e. One big main dose and two smaller ones, all n35 7s

OSR is two splits but first one is N25 with more sulphur but I'm thinking of swapping this dose back to granular just to keep all the liquid the same grade.

 

[Brisel]

I'd be keen to hear what new season liquid prices are. I used N30.5 10.8SO3 here this season & it gave a bit too much S according to PLANET recommendations. Next year I'll use N32 9SO3. N35 7S isn't really enough for cereals, never mind oilseed rape. Kieserite or manures might top it up so it's down to your own system.

Yara liquid prices have been the same pence/kg N as quality AN in the past. The savings or extra expense of liquid depends on lots of factors like forklifts/sheds/scorch/sprayer capacity/tramline width/tank capacity/labour/bowsers etc.

 

[spikeislander]

Yes I'm thinking 32 9 might be a bit kinder?

 

[Brisel]

Kinder? In what respect? They are all UAN based, so scorch will be a similar issue with all of them.

 

[db9go]

Dont get to hung up with this scorch issue it is not that great of an issue we have been on liquid now for 20 years and some times we may get a few tip scorches that is all and it soon grows out of it. We have used all different mixes and it does not matter they can all give a slight scorch.
All So if you want you can dilute with plain water.
When you have finished you can pump what is left back in to storage which you have a job to do with solid fert

this year is the first time we have scorched wheats in about 7 years of liquid use , it really wasn't too bad and was over it in a week as soon as it rained, the crop was so stressed in the drought that even the BWstar scorched the crop so I think it was unavoidable this spring


It's really not a big deal IMO unless you are daft with it


AN based mixes are worst, AN is not a nice form of N either for soil and plant health IMO so best avoided, its also expensive vs alternatives
