Is this sulphur?

[Zippy768]

Got two bags that look like this, on the right of the picture.

On the left is what 4 other bags have looked like so far, and what bags I have checked in the stack.
Should be 40n 14s.
Looks to me like the other way around?

I'd be getting on to them about that.
As you say it looks more sulphur than n on the right

I'm gonna have to spread it now as in spinner. Will half rates and go over twice as half the spinner load seems OK.
Got pics

Keep a sample
video how you take it to show you did it properly
get it tested

the problem will be evenness of spread
i calibrate every batch with spreader trays from Amazone
my spreader check guy says the Amazone trays give similar readings to their check

Got 2 samples, informed the sales person of the issue.
Early suggestions is that the more transparent granules maybe Amonimum Sulphate, and that it's a different source of. Though all the same batch number on bags yet bags look visibly different with what's in there.

How would you get some tested? They haven't anyone about.....

It’s up to them to get a satisfactory answer for you if that involves them testing it

That definitely looks like ammonium sulphate on the right

This stuff...

That definitely looks like ammonium sulphate, your fertiliser is a blend to achieve the analysis stated on the bag.

The opaque granules

[Zippy768]

Ok, to be clear.
On the left of the picture is what I would expect a 40:0:0:14s product to look like.
But some bags have way more opaque granules in.

Early suggestions from sales is that nothing wrong with Blend and that the difference is from a different source of ammonium sulphate resulting in it looking different.
Same batch number and bags - visibly - definitely contain different product.

Needs analysis doing on it.

Blending is not an exact science, it's entirely possible there's a mistake.
Trouble is if it's 25n instead of 40, you'll obviously be massively under dosing the crop it's going on.

Yep

What's usually in 40N14S? My calculator can't get to that with urea and AS alone. Or is it 14 SO3?

That sample looks to have far too much AS in it.

If it is supposed to be 14% SO3, then the urea should be 76% of the blend, by weight.

75% the other way is only 27N.

 

[Luke Cropwalker]

If the blend is supposed to be 40-0-0-14 and it is made up of urea and ammonium sulphate the each tonne of fertiliser should be made up of around 763kg of urea and 263kg of ammonium sulphate.

All sorted.
Remaining bags will be taken tomorrow and replaced, with a few extra bags compensation.
Thank you Mole Valley for understanding, eventually

 

[David.]

A FEW extra, wow!

What was actually in the bags ?
