What does the Haber process produce?

1. Nitrogen from the air is useless to plants until it is fixed into a soluble compound. 2. The Haber process combines nitrogen gas with hydrogen gas. 3. The product of that combination is ammonia gas. 4. The ammonia is then the starting point for nitric acid, ammonium nitrate and urea. _Source: Siyavula Physical Sciences Grade 12 (Everything Science, CC BY 4.0), Chapter 14: The chemical industry_
