Explain that industrial production of NPK fertilisers can use several raw materials and integrated processes. (Chemistry only)

In the subtopic Production and uses of NPK fertilisers, this learning objective focuses on explain that industrial production of NPK fertilisers can use several raw materials and integrated processes. (Chemistry only). Within The Haber process and the use of NPK fertilisers, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only and NPK fertiliser. Integrated fertiliser production means the combined use of multiple raw materials and chemical processes to manufacture nitrogen, phosphorus and potassium salts for NPK fertilisers. Avoid students often think that NPK fertilisers are made from a single raw material; instead remember that NPK fertilisers can be produced using several raw materials and integrated processes. For exam answers, make sure to memorize the various raw materials used in the industrial production of NPK fertilisers, such as nitrogen, phosphorus, and potassium sources.
