Fertilisers
Nitrogen, phosphate and potash fertilisers as a distinct group in world commodity trade.
How to read the number
Their price is tied to gas and to the harvest at once: gas is the feedstock for nitrogen fertilisers, and the harvest decides what a buyer can afford.
When the metric lies
The market splits by nutrient, and nitrogen, phosphate and potash prices move differently. Judging a particular producer by a general fertiliser market misses what it actually makes.
