Russian fertilizer exports have largely relocated from the Black Sea to the Baltic, and that concentration is now the clearest supply risk sitting in front of growers planning next season's inputs. Russia lost its ammonia export route through Ukraine and much of its Black Sea export capacity, so ammonia, urea and phosphate increasingly leave through Baltic terminals such as Ust-Luga instead. Ukraine has now shown it can reach that coast. For anyone buying fertilizer, the practical consequence is that a single corridor carries a growing share of the world's tradeable supply.
Mike Castle, Senior Commodities Economist at StoneX, covers grain, oilseed and fertilizer markets from Kansas City, and Arlan Suderman, Chief Commodities Economist for StoneX Group's FCM Division, oversees the firm's commodity market intelligence across agriculture, energy and metals. Fertilizer sits where their coverage overlaps, since ammonia, urea and phosphate flows depend on the same energy inputs and export corridors that Suderman follows through the Black Sea and Baltic and that Castle tracks through to the US application season.
"Ukraine had struck one of Russia's ports on the Baltic, which would be highly significant because they do a lot of exporting through the Baltic", Suderman said of the chatter moving through the market overnight. Russian fertilizer exports now run mainly through Baltic terminals, after Russia lost its ammonia export route through Ukraine and much of its Black Sea capacity. Russia had also been railing wheat north to the same coast, which stacks grain and fertilizer volumes onto shared infrastructure. Consequently, one corridor now carries a share of global fertilizer trade that used to be split across two, and any disruption along it reaches more of the market than it would have before.
Phosphate is the fertilizer most exposed in this corridor, because producing it requires ammonia and sulfur that many producers have to bring in first. The limiting factor, Castle explains, sits upstream of the finished product, since "the ammonia and sulfur side are really the big limiting factors there, and a lot of producers are reliant on importing those to produce their own phosphate". When that import step breaks, buyers have to source finished phosphate instead, and there are only so many places to go, with Morocco and Russia holding most of the tradeable volume and "only so much to go around". Notably, Russian natural gas supply feeds the same chain, so damage to energy infrastructure reaches phosphate output downstream rather than only slowing shipments.
Fertilizer supply risk for the 2027 crop is building rather than confirmed, and if it does materialize the market will ration demand through price rather than through allocation. Phosphate is the more forgiving of the two, since soils in good condition can carry a grower through a season or two without a normal application, whereas nitrogen is harder to skip. Many growers already apply a little more nitrogen than they need, so pulling back 5 to 10 percent may not show up in yield, though cuts beyond that start to. According to Suderman, "some of those places that are least able to afford the higher prices of fertilizer will be the ones that will see the heavier rationing".

Russian fertilizer exports have concentrated into the Baltic after the Black Sea and Ukrainian routes closed, and Ukraine has now shown it can reach those ports. Phosphate is the input most exposed, because producing it depends on imported ammonia and sulfur that travel the same disrupted corridors.

Potash sits inside a fertilizer market gripped by missing sulfur and absent Chinese phosphate, and its own supply is comfortable. Freight is what keeps the price from softening, and it reaches every railcar, barge and vessel in the trade.
