I can answer that question by saying that this 100% increase occurred the year before. The fertilizer market is a free market, just like any other commodity. As Mr. Thompson mentioned, the demands had already increased. In addition, the COVID‑19 pandemic caused a decrease in capacity. China stopped exporting fertilizer for a long period of time.
So several factors have contributed to the price increases, in a free market, before the war in Ukraine and before the sanctions and the 35% tariff.
