Didn’t I tell you this a year ago!
We have gone much, much more to liquid. But still have 210t of Nitram in the shed.

Been looking through this old thread. We have satellite images now for our farm in June 2018. Obviously something has gone wrong. I'm so disheartened with solid fertiliser. After we had SCS in 2016 I sort of put the issue to bed a bit. This image shows I was wrong to do so. I never really did explain all the rubbish tray tests I got compared to SCS getting a decent result. I think I'm going to get them in again and put my trays next to theirs and compare the two side by side. Wish I hadn't bought so much Nitram (only upside was we bought it at £204/t) and ordered liquid instead.
What are the lighter areas?
Looks a lot like my osr did the first year I got my 28 m slug pelleter.
The pellets didn't reach so had stripes on between tramlines that were thin.
Showed up dramatically.
No we melt urea down into liquid sometimes depending on price. We did try and spin abit to 36 about 3 or 4 years ago but wasn’t very good.What did you tell me? You went back to mainly solid last year or the one before didn't you? Funnily enough our new (old) Omex tank has come from my uncle who is giving up liquid!
I think machines should be supplied with trays so an operator can test himself . It's fine having the guy out but batches could change. Kuhn have a guide to follow in the manual how to do tray tests but don't know if other brands of spreader manuals show this?+1 for ringing SCS my Kuhn pattern looked a million times better than that.
Why do you use solids when you have capability for liquid ? 11% out on the most important input wouldn't be acceptable to me ......... and that's before wind etc
Because we are slowly ramping up liquid use each year. This year we are majority liquids, but doing solid on OSR for logistics reasons and Nitram on wheat as a last dressing due to sprayer pressure and scorch worries.
Looks perfectly acceptable to me, I doubt any further adjustment on the vanes would improve that.Who thinks this is an acceptable tray test? Good enough or not? Readings taken at 0m (I), 3m (II), 6m (III), 9m (IV) and 12m (V)(didn't have five collecting things). Readings on the (non-linear) scale were I - 8.5, II - 8.5, III - 8.5, IV - 9 and V - 9.5.
This is better than I have got before, but it's still not perfect. 11% difference between high and low.

Personally I'm very happy with my Amazone spreader with its trays and self calibration system, very straightforward and would rather be able to test if myself whenever and as frequently I want than pay someone else once a year.
I used to get results like those and found it difficult to correct, it was always over throwing the product, but by reducing pto rpm from 540 to 510/520 it is spot on!

Probably wrong discs overthrowing. I had this problem using the V3 discs on 24m trams. V2 discs solved the problem. This is on a ZA-M.I find the vane change suggestions from the Amatron only seem to make things worse! Remember the fifth reading was the worst (not shown in the picture).

The V3s are supposed to cover trams between 24 and 36m and the V2s 18-24m I think. Just remembered, my model is actually a ZA-V not an M.We have OM 24-36m discs. What does V3 and V2 refer to?
