Fertilizer is made from natural gas.
Your President doesn’t allow the production of natural gas, or any other form of energy, dummy.
Next time you whine about the price of gas remember what you just said.
Natural gas is something we have in excess - so send your cards and letters to Congress and quit using Russia as your supplier. When did you think that would be a good idea? Same time Germany thought it'd be a good idea to get their gas from Russia?
