A farmer spreads nitrogen fertilizer in his wheat field in Blecourt, France, May 27, 2021. Russia, under financial sanctions, is a major producer of fertilizer and natural gas, key in making nitrogen products to boost yields of corn and other crops. Since Russia's February invasion of Ukraine, Europe started weaning itself off Russian natural gas and a pipeline transporting ammonia from Russia to a Ukraine port shut down. European countries typically buy most of their imported urea, a form of nitrogen fertilizer, from North Africa, but are now purchasing it further afield, Wallace said. EU nitrogen prices eased in mid-October as some European plants resumed production due to softening natural gas prices, he said.
