Where to buy Fertiliser spread testing kit

[KB6930]

If the top picture is after two passes (one up, one down the next tram) then it is unlikely he will be able to spread that fert at that width. No matter how much adjustment his spreader has. (or they are very thin tubes)

No one pass as stated they're matching at halfway due to the spread width the machine is on it's limits at 30m but the app gives settings so should be possible.

I'm lucky my current machine can spread our width and wider no bother and the machine of a different brand that I'm waiting to arrive should be more than capable as well

Looking again, if the r/h tube in your sample is the one furthest away from the spreader, then it's a good example of the point Dr Wazzock was making.

Most the large prills are in that tube, and most the small prills in the one nearest the tractor.

No my tubes the pic with 3 is putting less behind the tractor . The centre tube is 12m from the tractor

I've done 2 tramlines so that's in between 2 on one side of the spreader as per the book so I'd have ended up with striping in the middle of the tramlines if I'd not checked it

but the next pass would be the same and balance things out

In yours Tube1 and 3 are similar.

Centre tube is high, so not an easy problem to solve.

This is a pattern not a width problem. (or a pattern problem caused by trying to spread to wide)

shorten 1 of the vanes?
or retard the angle?

Very easy to solve I had it sorted I'm 10 mins just pull the width in a bit . Moved it 4 letters on the scale. Kv spreader

thats how far out guesswork from trying to gauge the spread charts is....

I haven’t read the whole thread but I have a complete set that I no longer need if you want to make an offer.

So when I go out into my field of OSR which varies in height and density massively across the field, with a 7 mph wind gusting to 15 mph, lurching through rutted pot holes tramlines what use is a tray test done in perfect conditions? I admire the efforts made here to build your own test kit, but I call the money making exercise now inflicted upon us by yet another layer of self made “indispensable” experts largely bollox to all practical intents and purposes.

A lot more use than not doing it at all .

When I was young and naive I would spend half the day messing about with test bucket and stop watch, etc then egg trays in the field. After a few years of experience it became quite apparent that the manufacturers recommended settings were as good as what it would get then fine tuned for rate by how many bags you actually used on the first field and what it looked like on the ground. All you are doing with these snap shot tray tests etc is getting a setting that works for that particular bag and we all know how much they vary. This is the difference between the approach of practical pragmatic folk at the coal face compared with clipboard wielding technocrats IMO. But carry on. By the time you are on your second test I’ll have finished spreading for the day and be on to my next job. You will be rained off with it half finished. You need to get on with it in this job. That’s not much time for navel gazing.

I finally invested in the Amazon mats and signed in to the app. Can test as many times/products as I like now.
It's a faff but gives me (a bit more) peace of mind that I'm not far enough out to strip it.
I always struggled to spread cropmaster and heartland evenly, swear it was seperating it out somehow.
I've renewed the spreader, bought the mats and overspent on Nitram but no stripes so far.

How many acres and tonnes are you doing in a year ?

By the time I'm across everything I'll do 5000 acres per year roughly 300t at home and plenty contracting jobs .
And I can assure you from personal experience that if I don't tray test I'll stripe something.

So pick reasonably calm conditions and test it . Set it right for the best conditions and it'll be the best it can be in the worst of conditions.

But you just crack on and stop over thinking what's in this thread

Fair enough if big acreages, volumes and contracting work. We are comparing apples and pears.

Exactly.

 

[davidroberts30]

funnily enough i would be the other end of the scale to @KB6930 so with me every acre counts.
5 acre striped and applied wrong is a massive % of my crops!
I've used 3 different kuhn spreaders so far this year and no spread charts, no basics starting points.
any guestimates at the charts =massively wrong settings
i have heard a rumour of a guy that set his amazon to the charts and spread then really striped the corn so no charts are infallible
2 hours spent checking the spreader to basic settings then running 3 or 4 try tests is well worth it

If your going to do a job, do it right, then at least you know when your bouncing around in the seat, watching the fert your spreading being blown back towards you and the rape shimmering like the sea off Bondi beach, you can sleep well in your bed knowing the coefficient of variation was small and the spreader was set right
