How is agricultural fertilizer made


Based on the two main end products, ammonium nitrate and urea, different fertilizer types are manufactured by mixing with ingredients such as phosphorus and potassium to form NPKs, dolomite to form CAN or by mixing urea and ammonium nitrate solution to make UAN. Phosphorus fertilizers are produced by acidulating phosphate rock.

Nitrogen fertilizer is made by capturing nitrogen from the air and combining it with hydrogen derived from natural gas. This production method is called the Haber-Bosch process. Phosphorus is involved in many processes critical to plant development.
