Superphosphate fertiliser, produced by reacting phosphate rock with sulphuric acid, is the foundation of modern industrial agriculture. The reaction converts the insoluble calcium phosphate minerals in phosphate rock into soluble calcium superphosphate, which plants can readily absorb. Without synthetic phosphate fertilisers, the crop yields that support Oceanyka's population density in its more fertile regions would be impossible to sustain. Oceanykan fertiliser production benefits from both the continent's abundant phosphate rock deposits and its ample, high-quality agricultural land.
