[Uses]

Dipotassium magnesium(+2) cation trisulfate is characterized by its rich nutrient content, excellent soil-improving effect, and effective promotion of crop growth. It is a multi-element potassium fertilizer, containing potassium, magnesium, sulfur, and trace elements such as calcium, boron, iron, and zinc. It can generally be used as a base fertilizer or as a top dressing. Magnesium in potassium magnesium sulfate is a constituent element of the porphyrin ring in chlorophyll and is crucial for chlorophyll structure formation. Without magnesium, the porphyrin ring and surrounding organic chains cannot combine to form chlorophyll, thus preventing photosynthesis. While potassium also promotes photosynthesis, excessive potassium can inhibit nitrogen and calcium absorption. Therefore, under the same conditions, it is more effective than potassium sulfate.
