Ammonia is also a basic building block for ammonium nitrate fertilizer, which releases nitrogen, an essential nutrient for growing plants, including farm crops and lawns.
About 90 percent of ammonia produced worldwide is used in fertilizer, to help sustain food production for billions of people around the world.
The production of food crops naturally depletes soil nutrient supplies. In order to maintain healthy crops, farmers rely on fertilizer to keep their soils productive.
Fertilizers also can also help increase levels of essential nutrients like zinc, selenium and boron in food crops.
