Remembering volatilsation, striping in the first breath of wind & how little you get into the hopper?
Sulpher 25 p
Did you buy any N in straight? If so I'd use that to work out the N value of the fertiliser and then you'll be left with the S.
Or just steal one of my figures depending on what your opportunity cost would have been.
You get the same N in the hopper just lighter to save compaction.
I assume you 40p number is S as So3 ??
No, S as S.
My calcs were:
AnS at £247
= 21% N (210kg) and 24% S (240kg)
N at 70.4p/kg x 210kg is £147.84
£247 (total price) - £147.84 (assumed N value) = £99.16.
£99.15 for 240kg S works out at 41.31p/kg S
Either that....or i've made a mess somewhere!
Isn't the 24 S in AS 24% SO3 and not 24% elemental S ?
Elemental S would not be very available
Elemental S is 2.5x so3 I think ?
Nitram Nov delivered £292/t so 85p/kg N
Nuram N37 delivered August 2012 £312/m3 SG 1.29. I have lost the formula for p/kg. Can someone remind me please?
Interesting comparing this today and using @Steevo's 40p/kg S cost
cheapest N I bought was in DAP at £0.44p/kg (giving the P the same value as in TSP available at the same time)
The liquid we buy is the most expensive at £ 0.82p/kg but I had no committed tonnage - just phone and order as required
Looking at home brew UAS I could be making it today significantly cheaper I reckon that has got to be worth the effort for a saving like that ?? not to mention that its a better source of N as well
What quantitys of what products do you add to how much water? Also does it take much mixing? Or is it a secret recipe
What product/blend was that? Sounds an excellent price.
