Does it though?

Sold in litres, its 32% n, or does the 32 literally mean 32kg.
If its 32% n then surely it'll be heavier than 32kg.

Im totally new at this so really would like to know exactly how it works

That's the point of this discussion. Some is sold as a % of volume and some as a % by weight.

When spreading solid fertiliser, spreader is calibrated by weight.

Sprayer is calibrated by volume? Unless using a complicated formula.

yes buy in tonnes is easy and better for comparison - application rates need translation to volume but thats very simple / straight forward to do

I'm buying yara 19.0.0.19
By the cube.
Going by Brisel last post it has 19kg n per 100 litres
Right?
Wrong?
My first year on liquid but I work it out the same as Brisel. That would be 19kk if N and S03 in 100l Not sure whether I'm right or not.
Do know it means I am paying for the privilege of liquid fert at the moment but no stripes and crop all the way to the hedge is a novelty I am enjoying this year.

This liquid pricing is ridiculously complex.
Why can't they all sell the same units?
Weight and volume is impossible to keep track of.

I agree. It gets worse with farmers that make their own liquid as they are often quoting displacement figures in the mixing tank.

Water has a specific gravity of 1 which means 1000 litres weighs 1000kgs.

1000 litres of liquid fertiliser is water and dissolved nutrient so it is heavier than just water. The specific gravity tells you the actual weight so if the specific gravity is 1.25 then 1000 litres of the fertiliser will weigh 1250kgs. If you want to prove it to yourself then measure out 1 litre of fertiliser and weigh it.

If the product is declared by volume as per Chafer then that is the percentage of nutrient in 1000 litres so if it is 19-00-00-19 then there are 190kgs of N per 1000 litres or 19kgs per 100 litres.

If the product is declared by weight as per most other suppliers then that is the percentage of nutrient per 1000kgs (tonne) and you then need to convert that to calculate your application rate.

Brexit coming... list reasons for it going up and down here.........

All will be irrelevant to Yara & CF if grain goes up though.
They'll just pick whichever one of those reasons sounds plausible but safe bet the grain market will be what it tracks.

Hedging my bets a bit though. Bought all the compound for next years Spring barley on Monday as memory of what that stuff cost after grain hit £200 in 2007 still hurts but not done any straight N yet.
