Where do fertilizers come from?

Fertilizers covers phosphate fertilizers, phosphate rock, potash, urea. What moves them together: Natural gas prices (nitrogen), export restrictions in China and Russia, phosphate rock and potash geology, crop prices and farmer affordability.

Which fertilizers prices move together?

Within fertilizers, phosphate fertilizers and urea are the most closely linked: their monthly price changes correlate at 0.37. Correlation of monthly log price changes (not price levels), computed only over pairs with at least 90 overlapping months, the same method as the site-wide linked-prices report and the correlation calculator — this view is scoped to fertilizers alone, which the site-wide report's top pairs rarely include.

Green: prices that rise and fall together. Brown: prices that move in opposite directions. Thicker and darker lines are stronger correlations.
