Potassium magnesium sulfate, also known as potassium magnesium sulfide, aqueous potassium magnesium sulfate. It's a multi-element potash fertilizer. In addition to potassium, sulfur, magnesium, but also contains calcium, silicon, boron, iron, zinc and other elements. Potassium magnesium sulfate fertilizer generally contains S22%, K22%, Mg19.4%. Potassium magnesium sulfate fertilizer is made of natural ore containing potassium magnesium sulfate and processed through several processes, which can provide nutrients such as potassium, magnesium and sulfur for crops. Potassium magnesium sulfate fertilizer is weakly alkaline, more suitable for acid soil application, generally used as base fertilizer, can also be used as topdressing and foliar spraying fertilizer. Suitable for a variety of field and cash crops. Compared with potassium chloride and potassium sulfate, the fertilizer effect is equivalent or slightly better.
 

Magnesium sulfate fertilizer is one of the series products of multi-element potassium sulfate, which is a very important fertilizer. It can not only provide magnesium and sulfur elements to plants, but also loosen the soil, promote the growth and development of plant leaves, branches and roots, make the plant root system large, and accelerate the absorption of nitrogen, phosphorus and other elements in the soil, increasing the plant's ability to resist diseases. It is known as the "nutrient for plant growth and high yield". Plants cannot grow normally due to magnesium deficiency, so timely supplementation of magnesium is necessary to improve productivity and agricultural yield. Magnesium is an important component of chlorophyll and is essential for photosynthesis. It is an activator of many enzymes and can promote carbohydrate metabolism, nucleic acid synthesis, and phosphate conversion.
