Stocks of fertilizer are increasing. Why? It is kind of odd to see it rise. The solution is oil. Fertilizer is made from oil. Therefore, higher oil prices also increase the cost of fertilizer. Many businesses now boycott Russian oil, including those in the United States. As a result, the United States is drawing from its reserves, raising the price even more. Therefore, assuming that the price of fertilizer will likewise increase is not implausible. Of course, this will also have an impact on fertilizer stocks.
